Yttrium

Critical Metals Vital to Our Lives in Tight Supply

We begin 2012 similar to how we started 2011 when it comes to rare earth, rare technical metals and rare industrial metals. China has over 90% of production and refining. The US and EU governments are scrambling to legislate, source, produce, open and reopen mines. The West has decided to continue down the road of the idea that the markets will take care of the supply and price of these metals. What is alarming is how easily the West was lulled to sleep by China´s ability to supply the world its metals cheaply and efficiently. The West concentrated on making money trading stocks and futures that dealt with these commodities. China concentrated on building the most extensive mining industry in the history of man. Here in 2012 the Department of Energy in the USA has approved a spending bill that includes $20 Million to focus on the supply issues of these metals.

The metals I am speaking about are so vital to our everyday lives. These metals are found in your mobile phones, computers, LCD and LED TV´s, hybrid cars, solar power, wind power, nuclear power, efficient lighting and medical technologies. Here is a list of metals that have been deemed critical.

  • Indium RIM (Solar, Mobile Phones, LCD)
  • Tellurium RIM (Solar, Computers, Semi-conductors)
  • Gallium RIM (Solar, Mobile Phones, LED´s, Fuel Cells)
  • Hafnium RIM (Processors, Nuclear, Lighting, Plasma Cutting Tools)
  • Tantalum RIM (Capacitors, Medical Implants, Mobile Phones, Nuclear)
  • Tungsten RIM (Nuclear, Armaments, Aviation)
  • Yttrium REE (Lighting, Medical Technology, Magnets in Hybrids)
  • Neodymium REE (Magnets in Wind power, Super Magnets, Hybrid Vehicles)
  • Dysprosium REE (Computers, Nuclear, Hybrid Vehicles)
  • Europium REE (Lighting, LED´s, Lasers
  • Lanthanum REE (Hybrid Vehicles, Magnets, Optics)
  • Cerium REE (LED´s, Catalytic Converters, Magnets)

RIM=Rare Industrial Metal REE=Rare Earth Element

The supplies of these metals could hold back the production of green technologies. According to the latest report by the Department of Energy, ¨Supply challenges for five rare earth metals may affect clean energy technology deployment in the years ahead¨. If Green technology is to become main stream, the costs of these technologies have to reach cost parity with traditional energy sources. As long as there are serious supply issues with these metals the costs can´t reach these levels. The other option is finding alternatives like Graphene and Nanotechnologies.

The US and EU need supply chains of the metals that include both mining and refining of these metals. Relying on sovereign states for critical metals such as these, leave a nation vulnerable to outside influence in both politics and economics. Environmentalists have succeeded in influencing politicians to close mines throughout the West. Politicians have legislated the mining industry into the position it is in today. The Western nations must start now to build its supply chain or continue to be at the mercy of the BRIC (Brazil, Russia, India and China) nations for its metal needs.

The best the West can do now is provide, enough metals to meet its own demands. China has reached a point where it can now demand that certain industries produce their products there. If a company decides to try to produce the product in another country China will make producing that item cost prohibitive outside of China by raising the prices of the metals.

The demand for the products these metals are used to produce, are showing few signs of slowing down even in a so-called recession. Governments are subsidizing Green technology, people are buying mobile phones across the planet and everybody wants a nice flat screen TV. Will 2012 pass without countries truly taking this opportunity to fix the problem or will they step up and make the hard decisions which can put the countries back in control over their own destiny?

Electric cars to be hit by supply disruptions

The advancement of electric cars in the short-term could be affected by supply disruptions.

That’s the verdict of a new report from the US Department of Energy entitled 2011 Critical Materials Strategy, which looks at supply challenges for five rare earth metals – dysprosium, neodymium, europium, terbium and yttrium. These metals are used in magnets for wind turbines and electric vehicles or phosphors in energy efficient lighting. Meanwhile, other elements, including indium, lanthanum, cerium and tellurium, were found to be near critical.

According to the report, demand for almost all of the materials has grown more rapidly than demand for commodity metals such as steel – this has come from consumer products including mobile phones, computers and flat panel televisions, as well as clean energy technologies.

However, the report concludes that manufacturers of wind power and electric vehicle technologies are already looking into strategies to respond to potential shortages. It states that manufacturers are currently making decisions on future system designs, trading off performance benefits of elements such as neodymium and dysprosium against potential supply shortages.

As an example, wind turbine manufacturers are looking at gear-driven, hybrid and direct drive systems with varying levels of rare earth metal content while some electric vehicle manufacturers are pursuing rare earth free induction motors or using switched reluctance motors as an alternative to PM motors.

Critical Reading for Rare Earth Metals Investors

A quick search of media stories from the month of December, 2009 shows 24 clips including references to the 15 lanthanides and their related elements scandium and yttrium. By contrast, one day in December, 2011 produced 56 stories on the same resources. Even the tone of REE coverage has transformed over the years. Two years ago, an analyst piece from veteran metals consultant Jack Lifton titled “Underpriced Rare Earth Metals from China Have Created a Supply Crisis ” was a common headline as the world discovered that cheap supplies had left manufacturers vulnerable to a monopoly with an agenda. That supply fear made REE the investment de jour and sent almost all of the rare earth prices through the roof. In December of 2010, the headlines in big outlets like The Motley Fool announced that the “Spot Price of Rare Earth Elements Soar as much as 750% since Jan. 2010.”

Reality soon set in as investors realized that this was not a simple supply and demand industry. First, demand was still vague, subject to change and very specific about the type and purity of the product being delivered. Second, the ramp-up period for companies exploring, getting approval for development, mining, processing efficiently and delivering to an end-user was very, very long. Some became discouraged. That is why this year, the consumer finance site, The Daily Markets ran an article with the headline: “Why You Shouldn’t Give Up on the Rare Earth Element Minerals” by Gold Stock Trades Newsletter Writer Jeb Handwerger.

Through it all, Streetwise Reports has focused on cutting through the hype to explain what is really driving demand, how the economy and geopolitics shape supplies going forward and which few of the hundreds of companies adding REE to their company descriptions actually had a chance of making a profit.

Back in June of 2009, in an interview titled “The Race to Rare Earths,” we ran an interview with Kaiser Research Online Editor John Kaiser that concluded “China’s export-based economy, once dependent on American greed, is now but a fading memory. While the U.S. was busy printing and preening, the Chinese were long-range planning. But America wasn’t the only country caught off guard by China’s strategic, if surreptitious, supply procurement.” Even while other analysts were panicking, Kaiser was pointing out how investors could be part of the solution–and make a profit in the process.

“For the juniors, the opportunity right now is to source these projects. They get title to them, and when these end users want to develop them, they’re going to have to pay a premium to have these projects developed,” Kaiser said. “So it will not be economic logic that results in these companies getting bought out and having their deposits developed. It’ll be a strategic logic linked to long-term security-of-supply and redundancy concerns. And we’re seeing that sort of psychology at work in this market. It’s a bit of a niche in this market. Not as big as gold, but it is an interesting one because of the long-term real economy link implications.”

After years of covering the space by interviewing the growing chorus of analysts and newsletter writers singing the praises of rare earth elements, in June of 2011, we launched The Critical Metals Report to give exclusive coverage to the entire space, including rare earth elements, strategic metals and specialty metals. One of the first experts interviewed was Emerging Trends Report Managing Editor Richard Karn in an article called “50 Specialty Metals under Supply Threat.” He warned that investing in the space is not as simple as some other mining operations. “The market is just starting to become aware of the difficulty involved with processing these metals, which, in many cases, more closely resemble sophisticated industrial chemistry than traditional onsite brute processing. Putting flow sheets together that process these metals and elements economically is no mean feat.”

In this early article, Karn busted the myth that manufacturers would find substitutions, engineer out or use recycled supplies for hard-to-access materials. “The advances we have seen especially in consumer electronics over the last decade and a half have not been driven by lone inventors or college kids tinkering in their parents’ garages, but rather by very large, well-equipped and well-staffed research arms of powerful corporations. The stakes are high and if a certain metal is critical in an application, they will buy it regardless of the price,” he said.

Similarly, a July 2011 article for The Critical Metals Report featured Energy and Scarcity Editor Byron King sharing “The Real REE Demand Opportunity” driven by the automobile industry and beyond. He was one of the first to point out that not all rare earths are the same with Heavy Rare Earth Elements demanding big premiums.

“Going forward, the serious money will be in HREEs, which have a lot of uses other than EVs,” King said. “For example, yttrium is used in high-temperature refractory products. There’s no substitute for yttrium. Without it, you can’t make the refractory molds needed to make jet-engine turbine blades. If you can’t make jet-engine turbine blades, you don’t have jet engines or power turbines. The price points for these HREEs will reflect true scarcity and unalterable demand. People will bite the bullet and pay what they have to in order to get the yttrium.”

House Mountain Partners Founder Chris Berry also addressed the impact of electric vehicle demand on vanadium, a popular steel alloy strengthener now being used in lithium-ion batteries in the interview “Can Electric Vehicles Drive Vanadium Demand? “

“The use of vanadium in LIBs for EVs is not significant yet, but could eventually become important as the transportation sector electrifies. One of the real challenges surrounding LIBs is settling on the most effective battery chemistry. In other words, what battery chemistry allows for the greatest number of charge recycles, depletes its charge the slowest and allows us to recharge the fastest? Today, based on my research, lithium-vanadium-phosphate batteries appear to offer the highest charge and the fastest recharge cycle. It seems that the lithium-vanadium-phosphate battery holds a great deal of promise, offering a blend of substantial power and reliability. I am watching for advances in battery chemistry here with great interest,” Berry said.

In September, Technology Metals Research Founding Principal Jack Lifton shared his insights on why some junior REE companies are prospering while others wither and die. In the article, “Profit from Really Critical Rare Earth Elements,” he said: “Rare earth junior miners are now being culled by their inability to raise enough capital to carry their projects forward to a place where either the product produced directly or the value to be gained from the company’s development to that point by a buyer can be more profitable than a less risky investment. The majority of the rare earth junior miners do not understand the supply chain through which the critical rare earth metals become industrial or consumer products. Additionally, they do not seem to recognize the value chain issue, which can be stated as ‘How far downstream in the supply chain do I need to take my rare earths in order to be able to sell them at a profit?’”

Then Lifton made this important point for Critical Metals Report readers. “It is very important for the small investor to understand that the share market does not directly benefit the listed company unless the company either sells more of its ownership or pledges future production for present, almost always sharply discounted, revenue.” As always, Lifton encouraged investors to follow the money to a specific end rather than the general market demand often envisioned by investors accustomed to the more defined gold market.

In October, JF Zhang Associates’ Principal Consultant and Chief China Strategist J. Peter Zhang shared his insights on “U.S. Manganese Supply as a Strategic Necessity.”

Manganese is now largely used largely in the production of low quality stainless steel, but is being incorporated into lithium-ion batteries. That increased demand is focusing attention on the limited supply outside China. “There really is no electrolytic manganese metals production in the U.S. or anywhere outside China except for a small percentage from South Africa. We don’t produce even a single ounce in North America. Relying on other countries to supply essential commodities (like oil for instance) is always a problem. If China suddenly decided to reduce production, or in the likely event that its domestic demand increases, the world would be out of options. Policymakers need to understand this risk and Congress needs to take action to minimize the potential impacts,” he said. “From the end of 2008 to 2009, China tied things up. Since then, the price has doubled, tripled and quadrupled. That should be a wakeup call. North America needs to either establish a strategic reserve system for critical metals or build production capacity to mitigate supply risk. I think there is some sense of urgency right now, but a lot more needs to be done.”

Picking the right junior is the trick. In the November article “Navigating the Rare Earth Metals Landscape” Technology Metals Research Founding Principal Gareth Hatch outlined the odds. “TMR is tracking well over 390 different rare earth projects at present; I can’t see more than 8-10 coming onstream in the next 5-7 years. Projects already well past exploration and into the development and engineering stage, and beyond, clearly have first-mover advantage.”

Just this month, in an interview entitled, “The Age of Rare Earth Metals” Jacob Securities Analyst Luisa Moreno compared the impact REEs will have on our daily lives with the transformation in the Bronze Age.

“There is an economic war over the rare earths, with China on one side and other industrialized nations on the other—Japan, the United States and the E.U. China is probably winning. It has decreased exports in the last few years and increased protection. It has attracted a great deal of the downstream business and it is positioning itself well. At this point, it produces most of the world’s rare earths, and prices are at record highs. Japan and the other countries have been left with few options, and those options are more expensive, such as substitution, recycling and adapting production lines to use less efficient materials.” Moreno then pointed to the seven companies that could come to the world’s rescue and usher in a miraculous new world of smaller, stronger, more powerful gadgets based on a steady supply of REE materials from reliable sources.

DOE report finds 5 clean-energy related REEs at risk in short-term

The substantial capex required for the development of a rare earths mine, compounded by major miners’ lack of interest in mining rare earths, may spell trouble in meeting future demand.

A report issued Thursday by the U.S. Department of Energy has determined supplies of five rare earths metals-dysprosium, terbium, europium, neodymium and yttrium-are at risk in the short term, potentially impacting clean energy technology deployment in the years ahead.

The 2011 Critical Minerals Strategy examined 16 elements for criticality in wind turbines, electric vehicles, photovoltaic cells and fluorescent lighting. Of those 16 elements, eight are rare earth metals valued for their unique magnetic, optical and catalytic properties.

Five rare earth elements used in magnets for wind turbines and electric vehicles or phosphors for energy-efficient lighting were found to be critical in the short term (present-2015).

Between the short term and the medium term (2015-2025), the importance to clean energy and supply risk shift for some materials.

Other elements-cerium, indium, lanthanum and tellurium-were found to be near-critical.

DOE’s strategy to address critical materials challenges rests on three pillars. To manage supply risk, multiple sources of materials are required. “This means taking steps to facilitate extraction, processing and manufacturing here in the United States, as well as encouraging other nations to expedite alternative supplies,” the report said. “In all cases, extraction, separation and processing should be done in an environmentally sound manner.

“Second, substitutes must be developed,” the report cautioned. “Research leading to material and technology substitutes will improve flexibility and help meet the materials needs of the clean energy economy.”

“Third, recycling, reuse and more efficient use could significantly lower world demand for newly extracted materials,” the DOE advised. “Research into recycling processes coupled with well-designed policies will help make recycling economically viable over time.”

The report also contains three in-depth technology analyses with the following conclusions:

· “Rare earth elements play an important role in petroleum refining, but the sector’s vulnerability to rare earth supply disruptions is limited.”

· “Manufacturers of wind power and electric vehicle technologies are pursuing strategies to respond to possible rare earth shortages. Permanent magnets containing neodymium and dysprosium are used in wind turbine generators and electric vehicle motors. Manufacturers of both technologies are current making decisions on future system design, trading off the performance benefits of neodymium and dysprosium against vulnerability to potential supply shortages.”

 · “As lighting energy efficiency standards are implemented globally, heavy rare earths used in lightning phosphors may be in short supply. In the United States, two sets of lighting energy efficiency standards coming into effect in 2012 will likely lead to an increase in demand for fluorescent lamps containing phosphors made with europium, terbium and yttrium.”

In their analysis, DOE found R&D plays a central role in developing substitutes for rare earth elements. In the past year, the agency has increased its investment in magnet, motor and generator substitutes.

“The demand for key materials has also been driven largely by government regulation and policy,” the report observed.

“Issues surrounding critical materials touch on the missions of many federal agencies,” said the DOE. Since March 2010, an interagency working group on critical materials and their supply chains convened by the White House Office of Science and Technology Policy has been examining market risks, critical materials in emerging high-growth industries and opportunities for long term-benefit through innovation.

The report also found that, in general, mining and metal processing expertise “has gradually declined in countries of the Organization for Economic Co-operation and Development, although the need to develop and retain such expertise has received increasing attention in recent years.”

While the number of REO-producing firms located outside of China is small, the proliferation of new rare earth companies “could help ease market concentrations in the years ahead,” the DOE observed. However, “one of the most significant requirements in the rare earth supply chain is the amount of capital needed to commence mining and refining operations…”

“The extraction and, in particular, the processing of rare earth ore is extremely capital intensive, ranging from $100 million to $1 billion of capital expenditure depending on the location and production capacity,” the report noted. “Bringing a greenfield mine to production likely costs in excess of $1 billion.”

“The estimated financial investment needed just to prove the resource (e.g., exploration and drilling) can be up to $50 million,” said the DOE. “The up-front cost of production capacity can range from $15,000 to $40,000 per tonne of annual capacity.’

“Unlike other commodities, rare earth mining generally does not appeal to the major global mining firms because it is a relatively small market (about $3 billion in 2010) and is often less predictable and less transparent than other commodity markets,” the report said.

“Additionally, the processing of rare earth elements into high-purity REOs is fundamentally a chemical process that is often highly specialized to meet the needs of particular customers,” the study noted. “It requires unique mineral processing know-how that is not transferrable to other mining operations. These factors reduce the appeal of rare earths production to the major mining companies, leaving the field mostly to junior miners.”

The report observed that smaller mining companies face a number of challenges, including being less well-capitalized than the majors and may find it difficult to raise money from traditional market. Certain macroeconomic conditions, particularly tight credit and volatile equity markets, can contribute to these difficulties.

“Successful public flotations require fairly advanced operations with proven resources, a bankable feasibility study and often customer contracts or off-take agreements in place that ensure some level of revenue,” the agency said. The DOE noted that Molycorp and Lynas Corporation have the largest capitalizations, “reflecting in part their expansion of large established mines.”

Lowman: Reliant on rare earth

Toyota Prius

Science … tells us that nothing in nature, not even the tiniest particle, can disappear without a trace. Nature does not know extinction. All it knows is transformation … and everything science has taught me … strengthens my belief in the continuity of our spiritual existence after death. Nothing disappears without a trace.

— Werner von Braun

What do Yttrium, Promethium, Europium and Luterium have in common? Although they may sound like a foreign language, these rare earth elements comprise the backbone of new technologies for the 21st century. Seventeen chemical elements, also called rare earths, are appended to the existing periodic table of elements, and their relatively new discoveries have advanced the electronics industry. Yttrium, when alloyed with other elements, forms part of aircraft engines; Promethium is an essential component of long-lived nuclear batteries; Europium powers images in flat-screen televisions; and Luterium detects radiation in PET scanners (positron emission tomography) used for medical research. Many new technologies — hybrid cars, televisions, cellphones, computer hard drives, camera lenses, and self-cleaning ovens — owe their success to rare earth elements.

The Prius alone contains rare earth elements for its LCD screens, electric motor and generator, headlight glass, catalytic converter, UV windows and mirrors; other cars require similar components to provide competitive features for buyers. The magnets under the hood of a Prius are some of the most powerful on the planet. Different from older technologies, they use rare earth elements to charge the battery and turn the wheels.

Without rare earth elements, your iPod earbuds would still be large, old-fashioned and unwieldy headphones.

As the world’s technologies become increasingly dependent on rare earth metals, their reserves become more valuable. Half the world’s rare earth deposits are in China, which mines almost 100 percent of global supply. Because China recognizes its own increasing needs for new technologies, the country recently reduced rare earth element export quotas by almost 40 percent in 2010.

So what will other countries do to remain competitive in the high-technology market? The answer: Train the emerging generation in STEM education — science, technology, engineering and math — to develop new technologies.

In North Carolina, hubs like Research Triangle Park and Raleigh’s new Nature Research Center are ideal incubators for the next generation of scientists and engineers. Researchers are working around the clock to design products that do not require rare earth elements. At Ames Laboratory in Iowa, scientists are trying to create magnets devoid of any rare earth metals. General Electric is applying nanotechnology to wind turbines as part of its clean-energy portfolio. Nanocomposite magnets will reduce the need for two rare earth metals: neodymium and dysprosium, which function to line up the magnetic field in wind turbines or hybrid cars.

Another strategy for minimizing the reliance on China’s rare earth deposits is to locate reserves closer to home. On California’s Mojave Desert, several rare earth mining operations are reopening. Another option involves improved recycling of cellphones and other products that contain rare earth elements.

The most economical solution is to reduce our reliance on rare earth elements altogether. Toyota is scrambling to develop technologies that do not require magnets utilizing rare earth elements in hybrid cars, and the television industry hopes to someday eliminate the need for Europium and Terbium in its screen imagery.

Training the next generation of scientists and engineers to inspire creative solutions is critical; otherwise, iPods, PET scans and plasma televisions may become increasingly limited in their production. After all, where will America be without scandium, a rare earth element alloyed with aluminum in baseball bats?

Rare Earth Elements are not the same as Rare Industrial Metals

Randy Hilarski has also released a video on this article that can be watched by clicking here.

I read articles from other writers who often refer to Rare Industrial or Technical Metals as Rare Earth elements. I would like to take some time and clear up the issue. I deal with RIM’s and REE´s on a daily basis. The two might both be considered metals but that is where the similarities end.

First we have REE´s or Rare Earth Elements. These metals consist of 17 metals, the Lanthanides plus Scandium and Yttrium on the periodic table of the elements. These metals are in a powder form, making them difficult to assay and store. One important factor that is often mentioned is that they are not rare. This is very true, but finding REE´s in large deposits is difficult.

In the mining sector REE mines are standalone mines, that focus on the mining and refining of REE´s exclusively. Currently around 97% of all REE´s are mined and refined in China. Historically REE mining and refining has been a dirty business, which has affected the environment around the mines. The elements Thorium and Uranium are often found along with the REE´s in the deposits causing the slurry to be slightly radioactive when processed. The use of highly toxic acids during the processing can also have serious environmental impact. Many companies are trying to open REE mines but they are meeting headwinds, as nations and people do not want these mines in their backyard.

Over the last few years China has dramatically cut its export of REE´s. This and the increased need for REE´s have caused a meteoric rise in the value of these metals. The one area that very few people talk about is the role of the media combined with speculators in raising the value of REE ETF´s in particular. For the last couple years REE´s were the rock stars of the metals. The news has calmed as of late, but the supply and demand factors that caused the metals to soar are still in place. Recently China closed it BaoTao mine until REE prices stabilize.

Rare Industrial Metals, RIM´s or Technical metals are another group entirely. The RIM´s are made up of metals used in over 80% of all products we use on a daily basis. Without these metals you would not have the world of the 21st century with our mobile phones, hybrid cars, flat screen TV´s, highly efficient solar energy and computers. Some of these metals include Indium, Tellurium, Gallium, Tantalum and Hafnium. These metals really are rare compared to the Rare Earth Metals which causes a great deal of confusion. These metals are in a metallic form, stable and easy to store and ship.

RIM´s are mined as a by-product of base or common metal mining. For example Tellurium is a by-product of Copper mining and Gallium is a by-product of Aluminum and Zinc mining. The mining of the RIM´s currently are for the most part at the mercy of the markets for the base or common metal mining. If the Copper mines of the world decide to cut production due to Copper losing value, this will have a huge impact on the amount of Tellurium that can be refined. Up until now, because of the previous small size of the RIM market, many companies do not feel the need to invest money into better technology to mine and refine these metals. The RIM´s would have to be valued much higher to gain the attention of the mining industry.

When China cut exports of REE´s they also cut exports of RIM´s. This put pressure on the value of these metals. RIM´s have increased in value, but nowhere near the meteoric rise of the REE´s. Most of the metals increased in value around 47% in 2010 and 25% so far in 2011. There is still a lot of room for growth in the value of these metals (not based on speculation like REE´s) as demand is exceeding supply now and in the future.

For Example, when REE´s and the stock market recently fell sharply the RIM´s came down slightly in value but have held their own extremely well. On a further note, according to Knut Andersen of Swiss Metal Assets, ¨Even though prices of the Rare Industrial Metals continue to go up in value, consumers will eventually only see a very small increase in the price of the end products, because there is so little of each metal used to produce these products. Also if the people can´t afford a smartphone they will still buy less expensive phones that still use the same Rare Industrial Metals¨.

The need for RIM´s has risen sharply over the years and will continue to grow at astronomical rates. China, India, South America and the whole of Africa with hundreds of millions of new consumers are now buying and using computers and mobile phones to name just a few products.

The future is bright for the technologies and the Rare Industrial Metals that make them work and for anyone who participates in stockpiling these metals now to meet future increased demand.

LED Applications Growing, Will Only Lead to More REE Demand

An end product’s supply chain can be far reaching, with parts or all of the upstream and downstream producers sometimes getting hit at different times by economic forces.

This appears to be happening in China’s domestic LED market, which has seen a marked fall-off in demand, according to the China Strategic Monitor. That’s hit pricing during the second half of this year.

“Investment plans are being curtailed both in the upstream and downstream compared to those presented last year,” according to the report. “Despite this there are many companies still attracted to the market and many pharmaceutical companies and even wineries in South China are moving into LED lighting products. Based on this trend the industry is likely to realize large-scale production capacity over the next 2 or 3 years and pricing for products should fall a further 20-30%.”

Industry watchers reckon 10% of LED-driven businesses in China could go bankrupt this year. And one chief executive, speaking at the recent China Industrial Development Forum for the Low Carbon Economy, said 90% of all China’s LED businesses are running at a loss.

Interesting. The country’s Guangdong province said earlier this month that it had exported US$3.81 billion worth of lighting products between January and August – that’s a 21% increase over the same time period last year.

“Customs authorities indicated that the main export market is still Europe and America with the two taking up 63.2% of the total,” a report said. “Though exports to Hong Kong, Japan and other ASEAN countries are up 60% on last year.”

The massive rise in LED exports is ascribed to the increasing trend of upgrading to energy-efficient lighting combined with the higher production values and quality in China, according to the report.

Still, various companies producing LED products complain that the industry is hit with high selling, raw material and R&D costs. So, while a company reports a 32% jump in LED sales in the third quarter of 2011when compared to 2Q10, the senior executives also talk about the need to implement structural changes, improve execution, reduce overhead costs and initiate job cuts.

Now, the LED industry uses a wide range of phosphor materials to convert light emission from LED chips into a different wavelength. So, combining a blue LED with one or more phosphors can create a white LED. Many of the phosphors used in LEDs contain rare-earth elements, the most common one being the yttrium aluminum garnet, which is doped with cerium.  Another phosphor, called TAG, contains terbium, while silicate and nitride phosphors are commonly doped with cerium or europium.

 Here’s a small example of how LED products are being used: Kingsun Optoelectronic Co has just installed more than 10,000 street lights containing one million high-efficiency white LEDs along 75 miles of roads in Shenzhen. Kingsun anticipates a 60-percent reduction in energy consumption compared to the high-pressure sodium fixtures that have been replaced in the upgrade.

And while LEDs are now widely recognized as emerging light sources for general illumination, it turns out that LED lighting can also be used in a broad range of life-science applications such as skin-related therapies, blood irradiation, pain management, hypertension reduction and photodynamic therapy, which, when combined with drugs, is finding its way into cancer research.

In other words, the LED industry is only now just starting to be exploited, meaning demand will grow across all sectors. Translation – more rare earths will be needed in producing these products as research advances are made and commercial producers become more lean and efficient.

Alternatives to truly ‘rare earth’

Science…tells us that nothing in nature, not even the tiniest particle, can disappear without a trace. Nature does not know extinction. All it knows is transformation…and everything science has taught me … strengthens my belief in the continuity of our spiritual existence after death. Nothing disappears without a trace.

Werner Von Braun

Yttrium, promethium, europium, and luterium may sound like mythological characters, but they’re rare-earth elements that comprise the backbone of new technologies for the 21st century.

Their discovery in recent years has advanced the electronics industry. Yttrium, when alloyed with other elements, forms part of aircraft engines; promethium is an essential component of long-lived nuclear batteries; europium powers images in flat-screen televisions; and luterium detects radiation in PET scanners used for medical research. Many new technologies owe their success to rare-earth elements.

The Prius, for example, contains rare-earth elements for its LCD screens, electric motor and generator, headlight glass, catalytic converter, UV windows, and mirrors; other cars require similar components to provide competitive features for buyers. Magnets under the hood of a Prius are some of the most powerful on the planet. Different from older technologies, they use rare-earth elements to charge the battery and turn the wheels.

As the world’s technologies become increasingly dependent on rare-earth metals, their reserves become more valuable. Half the world’s rare-earth deposits are in China, which currently mines almost 100 percent of global supply. Because China recognizes her own increasing needs for new technologies, it reduced rare-earth element export quotas by almost 40 percent in 2010.

What will other countries do to remain competitive in the high-tech market? Develop new technologies. Hubs like Research Triangle Park and Raleigh’s new Nature Research Center are ideal incubators for the next generation of scientists and engineers. Currently, researchers are working around the clock to design products that do not require rare-earth elements.

The most economical solution is to reduce our reliance on rare-earth elements altogether. Toyota is scrambling to develop technologies that do not require magnets utilizing rare-earth elements in hybrid cars; the television industry hopes to someday eliminate the need for europium and terbium in its screen imagery.

Training the next generation of scientists and engineers to inspire creative solutions is critical; otherwise, iPods, PET scans, and plasma televisions may become increasingly limited in their production. After all, where will America be without scandium, a rare-earth element alloyed with aluminum in baseball bats?

Higher Prices for Numerous Rare Earth-Based Consumer Products

Consumers can expect significantly higher prices for a variety of consumer goods that use rare earth metals as at least one raw material, according to Michael Silver, president and chairman of the board of American Elements, a global manufacturer of engineered and advanced materials including rare earth metals and chemicals.

“The U.S. consumer has no idea the number of simple everyday products that will be impacted by the huge jump over the last year in rare earth prices,” says Silver. “Over the past two decades rare earths have become essential to the state of the art version of hundreds of household goods.”

According to Silver, computers, cell phones and other electronics will see manufacturing costs rise as neodymium is in computer hard drives, cerium is in the monitor screens and other rare earths play a part in the electronics. Products that rely on small electric motors often contain Neodymium magnets which have increased many fold in price.

Possibly the biggest impact will be felt in the cost of the family car.

“Rare Earths are ubiquitous in automobiles, he says. “Cerium is in the window glass to prevent yellowing and used as a glass polish in production. Yttrium is in spark plugs. Neodymium is in the electric motors that run everything from seat adjustments to windshield wipers. Lanthanum is in the batteries for electric and hybrid vehicles.”

He predicts higher prices will ripple through not just cars but all forms of transportation. The applications effecting automobiles will equally raise costs for other forms of transportation such as flight and rail.

Silver cites light bulbs as an example that consumers do not realize are affected by rare earth prices as Cerium is in bulb glass and Europium acts as the phosphor in fluorescent lights.

He predicts dental care costs will rise. Silver reports amalgam used to fill cavities is now based on a rare earth compound to get the new all white fillings to show up on an X-Ray the way the old metal fillings did.

Neodymium is used in modern welding goggles to remove glare. “Neodymium is a very magical material with many unrelated capabilities. When dispersed in glass, it prevents the wave length associated with yellow-green light from passing through, which is the wave length that causes eye damage,” Silver says.

Silver says the consumer will ultimately feel the pinch in cable television costs as well. Fiber optic cables run on EDFA technology which stands for ‘Erbium-Doped Fiber Amplification’, a technology reliant on the availability of Erbium which has skyrocketed in price. Existing infrastructures will not be impacted. New and replacement lines will.

American consumers may even be impacted at tax time. Silver says, “Our entire military equipment budget will increase due to higher rare earth costs and that will translate into higher government demand for revenue.” Rare earths are essential in the production of bullet proof vests (yttrium), night vision goggles (gadolinium) and F-35 and F-22 Fighter Jets, Bradley Armored Vehicle and AIM-9x Sidewinder missiles (neodymium).

American Elements is the world’s manufacturer of engineered & advanced materials with corporate offices and primary research & laboratory facilities in the United States and manufacturing & warehousing in the United States, China, Mexico and the United Kingdom.

Critical Minerals, Elements, Metals, Materials

In this article I am going to take a look at three reports covering what the US and Europe consider critical or strategic minerals and materials.

In its first Critical Materials Strategy, the U.S. Department of Energy (DOE) focused on materials used in four clean energy technologies:

  • wind turbines: permanent magnets
  • electric vehicles:€“ permanent magnets & advanced batteries
  • solar cells: thin film semi conductors
  • energy efficient lighting: phosphors

The DOE says they selected these particular components for two reasons:

  1. Deployment of the clean energy technologies that use them is projected to increase, perhaps significantly, in the short, medium and long term
  2. Each uses significant quantities of rare earth metals or other key materials

In its report the DOE provided data for nine rare earth elements: yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, terbium and dysprosium as well as indium, gallium, tellurium, cobalt and lithium.

Five of the rare earth metals, dysprosium, neodymium, terbium, europium and yttrium€“ as well as indium, were assessed as most critical in the short term. The DOE defines “€œcriticality”€ as a measure that combines importance to the clean energy economy and risk of supply disruption.

Securing Materials for Emerging Technologies

A Report by the APS Panel on Public Affairs and the Materials Research Society coined the term “€œenergy-critical element”€ (ECE) to describe a class of chemical elements that currently appear critical to one or more new, energy related technologies.

“Energy-related systems are typically materials intensive. As new technologies are widely deployed, significant quantities of the elements required to manufacture them will be needed. However, many of these unfamiliar elements are not presently mined, refined, or traded in large quantities, and, as a result, their availability might be constrained by many complex factors. A shortage of these energy-critical elements (ECEs) could significantly inhibit the adoption of otherwise game-changing energy technologies. This, in turn, would limit the competitiveness of U.S. industries and the domestic scientific enterprise and, eventually, diminish the quality of life in the United States.”

According to the APS and MRS report several factors can contribute to limiting the domestic availability of an ECE:

The element may not be abundant in the earth’€™s crust or might not be concentrated by geological processes

An element might only occur in a few economic deposits worldwide, production might be dominated by and, therefore, subject to manipulation by one or more countries – the United States already relies on other countries for more than 90% of most of the ECEs identified in the report

Many ECEs have, up to this point, been produced in relatively small quantities as by-products of primary metals mining and refining. Joint production complicates attempts to ramp up output by a large factor.

Because they are relatively scarce, extraction of ECEs often involves processing large amounts of material, sometimes in ways that do unacceptable environmental damage

The time required for production and utilization to adapt to fluctuations in price and availability of ECEs is long, making planning and investment difficult

This report was limited to elements that have the potential for major impact on energy systems and for which a significantly increased demand might strain supply, causing price increases or unavailability, thereby discouraging the use of some new technologies.

The focus of the report was on energy technologies with the potential for large-scale deployment so the elements they listed are energy critical:

  • Gallium, germanium, indium, selenium, silver, and tellurium employed in advanced photovoltaic solar cells, especially thin film photovoltaics.
  • Dysprosium, neodymium, praseodymium, samarium and cobalt€“ used in high-strength permanent magnets for many energy related applications, such as wind turbines and hybrid automobiles.
  • Gadolinium (most REEs made this list) for its unusual paramagnetic qualities and europium and terbium for their role in managing the color of fluorescent lighting. Yttrium, another REE, is an important ingredient in energy-efficient solid-state lighting.
  • Lithium and lanthanum, used in high performance batteries.
  • Helium, required in cryogenics, energy research, advanced nuclear reactor designs, and manufacturing in the energy sector.
  •  Platinum, palladium, and other PGEs, used as catalysts in fuel cells that may find wide applications in transportation. Cerium, a REE, is also used as an auto-emissions catalyst.
  • Rhenium, used in high performance alloys for advanced turbines.

 The third report I looked at, “Critical Raw Materials for the EU” listed 14 raw materials which are deemed critical to the European Union (EU): antimony, beryllium, cobalt, fluorspar, gallium, germanium, graphite, indium, magnesium, niobium, platinum group metals, rare earths, tantalum and tungsten.

€œRaw materials are an essential part of both high tech products and every-day consumer products, such as mobile phones, thin layer photovoltaics, Lithium-ion batteries, fibre optic cable, synthetic fuels, among others. But their availability is increasingly under pressure according to a report published today by an expert group chaired by the European Commission. In this first ever overview on the state of access to raw materials in the EU, the experts label a selection of 14 raw materials as “€œcritical”€ out of 41 minerals and metals analyzed. The growing demand for raw materials is driven by the growth of developing economies and new emerging technologies.

For the critical raw materials, their high supply risk is mainly due to the fact that a high share of the worldwide production mainly comes from a handful of countries, for example:

China: €“ Rare Earths Elements (REE)

Russia, South Africa:€“ Platinum Group Elements (PGE)

Democratic Republic of Congo:€“ Cobalt

All four of the following critical materials appear on each list:

  • Rare Earth Elements (REE)
  • Cobalt
  • Platinum Group Elements (PGE)
  • Lithium

The key issues in regards to critical metals are:

  • Finite resources
  • Chinese market dominance in many sectors
  • Long lead times for mine development
  • Resource nationalism/country risk
  • High project development cost
  • Relentless demand for high tech consumer products
  • Ongoing material use research
  • Low substitutability
  • Environmental crackdowns
  • Low recycling rates
  • Lack of intellectual knowledge and operational expertise in the west

 Certainly the rare earth elements, the platinum group of elements and lithium are going to continue receiving investor attention,€“ they are absolutely vital to the continuance of our modern lifestyle. But there are two metals increasingly on my radar screen, one is on all three above critical metals lists and the other soon will be when/if production increases, and in this authors opinion, that’€™s very possible.

Cobalt

A critical or strategic material is a commodity whose lack of availability during a national emergency would seriously affect the economic, industrial, and defensive capability of a country.

The French Bureau de Recherches Géologiques et Minires rates high tech metals as critical, or not, based on three criteria:

  • Possibility (or not) of substitution
  • Irreplaceable functionality
  • Potential supply risks

Many countries classify cobalt as a critical or a strategic metal.

 The US is the world’€™s largest consumer of cobalt and the US also considers cobalt a strategic metal. The US has no domestic production, the United States is 100% dependent on imports for its supply of primary cobalt,€“ currently about 15% of U.S. cobalt consumption is from recycled scrap, resulting in a net import reliance of 85%.

Although cobalt is one of the 30 most abundant elements within the earth’s crust it’s low concentration (.002%) means it’s usually produced as a by-product – cobalt is mainly obtained as a by-product of copper and nickel mining activities.

Scandium

Scandium is a soft, light metal that might have applications in the aerospace industry. With a cost approaching $300 per gram scandium is too expensive for widespread use. Scandium is a byproduct from the extraction of other elements, uranium mining, nickel and cobalt laterite mines and is sold as scandium oxide.

The absence of reliable, secure, stable and long term production has limited commercial applications of scandium in most countries. This is despite a comprehensive body of research and a large number of patents which identify significant benefits for the use of scandium over other elements.

Particularly promising are the properties of :

  • Stabilizing zirconia: Scandia stabilized zirconia has a growing market demand for use as a high efficiency electrolyte in solid oxide fuel cells
  • Scandium-aluminum alloys will be important in the manufacture of fuel cells
  • Strengthening aluminum alloys (0.5% scandium) that could replace entire fleets with much cheaper, lighter and stronger aircraft
  • Alloys of scandium and aluminum are used in some kinds of athletic equipment, such as aluminum baseball bats, bicycle frames and lacrosse sticks
  • Scandium iodide (ScI3) is added to mercury vapor lamps so that they will emit light that closely resembles sunlight

Conclusion

The REEs, PGEs, Lithium and Cobalt are all truly critical to the functioning of our modern society. It’€™s easy to see why they are classified as critical or strategic. Scandium will increasingly find its way into our everyday lives and undoubtedly take its place on the various critical metal lists.

Access to raw materials at competitive prices has become essential to the functioning of all industrialized economies. Cobalt is one of those raw materials, so too will be Scandium.

Are these two critical metals on your radar screen?

If not, maybe they should be.

Thirteen Exotic Elements We can’t Live Without

From indium touchscreens to hafnium-equipped moonships, the nether regions of the periodic table underpin modern technology,€“ but supplies are getting scarce

AS YOU flick the light switch in your study, an eerie europium glow illuminates your tablet computer, idling on the desk. You unlock it, casually sweeping your finger across its indium-laced touchscreen. Within seconds, pulses of information are pinging along the erbium-paved highways of the internet. Some music to accompany your surfing? No sooner thought than the Beach Boys are wafting through the neodymium magnets of your state-of-the-art headphones.

For many of us, such a scene is mundane reality. We rarely stop to think of the advances in materials that underlie our material advances. Yet almost all our personal gadgets and technological innovations have something in common: they rely on some extremely unfamiliar materials from the nether reaches of the periodic table. Even if you have never heard of the likes of hafnium, erbium or tantalum, chances are there is some not too far from where you are sitting.

You could soon be hearing much more about them, too. Demand for many of these unsung elements is soaring, so much so that it could soon outstrip supply. That’s partly down to our insatiable hunger for the latest gadgetry, but increasingly it is also being driven by the green-energy revolution. For every headphone or computer hard-drive that depends on the magnetic properties of neodymium or dysprosium, a wind turbine or motor for an electric car demands even more of the stuff. Similarly, the properties that make indium indispensable for every touchscreen make it a leading light in the next generation of solar cells.

All that means we are heading for a crunch. In its Critical Materials Strategy, published in December last year, the US Department of Energy (DoE) assessed 14 elements of specific importance to clean-energy technologies. It identified six at “critical” risk of supply disruption within the next five years: indium, and five “rare earth” elements, europium, neodymium, terbium, yttrium and dysprosium. It rates a further three - cerium, lanthanum and tellurium - as “near-critical”.

What’s the fuss?

It’s not that these elements aren’t there: by and large they make up a few parts per billion of Earth’s crust. “We just don’t know where they are,” says Murray Hitzman, an economic geologist at the Colorado School of Mines in Golden. Traditionally, these elements just haven’t been worth that much to us. Such supplies are often isolated as by-products during the mining of materials already used in vast quantities, such as aluminium, zinc and copper. Copper mining, for example, has given us more than enough tellurium, a key component of next-generation solar cells, to cover our present needs - and made it artificially cheap.

“People who are dealing with these new technologies look at the price of tellurium, say, and think, well, this isn’t so expensive so what’s the fuss?” says Robert Jaffe, a physicist at the Massachusetts Institute of Technology. He chaired a joint committee of the American Physical Society and the Materials Research Society on “Energy Critical Elements” that reported in February this year. The problem, as the report makes clear, is that the economics changes radically when demand for these materials outstrips what we can supply just by the by. “Then suddenly you have to think about mining these elements directly, as primary ores,” says Jaffe. That raises the cost dramatically - presuming we even know where to dig.

An element’s price isn’t the only problem. The rare earth group of elements, to which many of the most technologically critical belong, are generally found together in ores that also contain small amounts of radioactive elements such as thorium and uranium. In 1998, chemical processing of these ores was suspended at the only US mine for rare earth elements in Mountain Pass, California, due to environmental concerns associated with these radioactive contaminants. The mine is expected to reopen with improved safeguards later this year, but until then the world is dependent on China for nearly all its rare-earth supplies. Since 2005, China has been placing increasingly stringent limits on exports, citing demand from its own burgeoning manufacturing industries.

That means politicians hoping to wean the west off its ruinous oil dependence are in for a nasty surprise: new and greener technologies are hardly a recipe for self-sufficiency. “There is no country that has sufficient resources of all these minerals to close off trade with the rest of the world,” says Jaffe.

So what can we do? Finding more readily available materials that perform the same technological tricks is unlikely, says Karl Gschneidner, a metallurgist at the DoE’s Ames Laboratory in Iowa. Europium has been used to generate red light in televisions for almost 50 years, he says, while neodymium magnets have been around for 25. “People have been looking ever since day one to replace these things, and nobody’s done it yet.”

Others take heart from the success story of rhenium. This is probably the rarest naturally occurring element, with a concentration of just 0.7 parts per billion in Earth’s crust. Ten years ago, it was the critical ingredient in heat-resistant superalloys for gas-turbine engines in aircraft and industrial power generation. In 2006, the principal manufacturer General Electric spotted a crunch was looming and instigated both a recycling scheme to reclaim the element from old turbines, and a research programme that developed rhenium-reduced and rhenium-free superalloys.

No longer throwing these materials away is one obvious way of propping up supplies. “Tellurium ought to be regarded as more precious than gold - it is; it is rarer,” says Jaffe. Yet in many cases less than 1 per cent of these technologically critical materials ends up being recycled, according to the United Nations Environment Programme’s latest report on metal recycling, published in May.

Even if we were to dramatically improve this record, some basic geological research to find new sources of these elements is crucial - and needed fast. Technological concerns and necessary environmental and social safeguards mean it can take 15 years from the initial discovery of an ore deposit in the developed world to its commercial exploitation, says Hitzman.

Rhenium again shows how quickly the outlook can change. In 2009, miners at a copper mine in Cloncurry, Queensland, Australia, discovered a huge, high-grade rhenium seam geologically unlike anything seen before. “It could saturate the world rhenium market for a number of years - and it was found by accident,” says Hitzman.

In the end, we should thank China for its decision to restrict exports of rare earths, says Jaffe, as it has brought the issue of technologically critical elements to our attention a decade earlier than would otherwise have happened. Even so, weaning ourselves off these exotic substances will be an immense challenge - as our brief survey of some of these unsung yet indispensable elements shows.

Precious Metals: Is Tellurium the new Gold?

Rare Industrial - Metal - Tellurium

Gold has been spectacularly popular among investors for the past couple of years.

Silver seems to be this year’s gold.

So, what’s next year’s silver gonna be?

According to Robert Jaffe, a physicist at MIT, tellurium could be a metal investor’s best new play.

“Tellurium ought to be regarded as more precious than gold — it is; it is rarer,” he tells New Scientist magazine.

An article by James Mitchell Crow in the June, 2011 issue of New Scientist, titled “13 Exotic Elements We Can’t Live Without,” points out:

We rarely stop to think of the advances in materials that underlie our material advances. Yet almost all our personal gadgets and technological innovations have something in common: they rely on some extremely unfamiliar materials from the nether reaches of the periodic table. Even if you have never heard of the likes of hafnium, erbium or tantalum, chances are there is some not too far from where you are sitting.

You could soon be hearing much more about them, too. Demand for many of these unsung elements is soaring, so much so that it could soon outstrip supply. That’s partly down to our insatiable hunger for the latest gadgetry, but increasingly it is also being driven by the green-energy revolution. For every headphone or computer hard-drive that depends on the magnetic properties of neodymium or dysprosium, a wind turbine or motor for an electric car demands even more of the stuff. Similarly, the properties that make indium indispensable for every touchscreen make it a leading light in the next generation of solar cells.

All that means we are heading for a crunch. In its Critical Materials Strategy, published in December last year, the US Department of Energy (DoE) assessed 14 elements of specific importance to clean-energy technologies. It identified six at “critical” risk of supply disruption within the next five years: indium, and five “rare earth” elements, europium, neodymium, terbium, yttrium and dysprosium. It rates a further three - cerium, lanthanum and tellurium - as “near-critical”.

Here are the 13 elements necessary for cleantech applications that may be winners in this year’s commodities portfolio:

Neodymium

New Scientist says:

These numerous uses make for a perfect storm threatening future supplies. In its Critical Materials Strategy, which assesses elements crucial for future green-energy technologies, the US Department of Energy estimates that wind turbines and electric cars could make up 40 per cent of neodymium demand in an already overstretched market. Together with increasing demand for the element in personal electronic devices, that makes for a clear “critical” rating.

Erbium

New Scientist says:

Erbium is a crucial ingredient in the optical fibres used to transport light-encoded information around the world. These cables are remarkably good at keeping light bouncing along, easily outperforming a copper cable transporting an electrical signal. Even so, the light signal slowly fades as it racks up the kilometres, making amplification necessary.

Tellurium

New Scientist says:

In 2009, solar cells made from thin films of cadmium telluride became the first to undercut bulky silicon panels in cost per watt of electricity generating capacity.

Because the global market for the element has been minute compared with that for copper - some $100 million against over $100 billion - there has been little incentive to extract it. That will change as demand grows, but better extraction methods are expected to only double the supply, which will be nowhere near enough to cover the predicted demand if the new-style solar cells take off. The US DoE anticipates a supply shortfall by 2025.

Hafnium

Hafnium’s peerless heat resistance has taken it to the moon and back as part of the alloy used in the nozzle of rocket thrusters fitted to the Apollo lunar module. Since 2007, though, it has also been found much closer to home, in the minuscule transistors of powerful computer chips.

That’s because hafnium oxide is a highly effective electrical insulator. Compared with silicon dioxide, which is conventionally used to switch transistors on and off, it is much less likely to let unwanted currents seep through. It also switches 20 per cent faster, allowing more information to pass. This has enabled transistor size to shrink from 65 nanometres with silicon dioxide first to 45 nm and now to 32 nm.

US Rare Earth Public Policy Needs to Move From Studies to Actions

One of my favorite consulting slogans of all time “Analysis Paralysis”€” aptly captures the state of US public policy on rare earth metals and critical minerals (not to confuse the two). After our story last week on testimony presented to the House Committee on Natural Resources, urging the Committee to take action on a number of bills involving rare earth metals, we heard from Jeff Green, a well-known rare earth and specialty metals lobbyist. Green wanted to share some of his perceptions of current legislation and where he thinks US public policy needs to go to begin addressing some of the strategic supply constraints.

Rare Earth Stockpiling

“€œA lot of people are misperceiving what is being debated related to a stockpile”,€ Green said. “€œThe only proposal on the table involves a new version of the RESTART Act (Rare Earths Supply Chain Technology and Resources Transformation (RESTART) Act of 2011) that calls for a 250-ton inventory of rare earth alloy and rare earth magnets.”€ The concept involves creating a small vendor-managed inventory that could be drawn down in a time of war. The “stockpile” would involve the government essentially buying up capacity from one of the US mining firms, as opposed to actually taking title and inventory. This approach, according to Green, provides critical domestic demand, a key component of re-starting US industry.

An Incremental Approach€“ the RESTART Act

Another approach, one that Green favors, was offered by Rep. Mike Coffman (R-Co.) as an amendment to the Fiscal Year 2012 National Defense Authorization Act. It requires the DOD to create a Rare Earth Inventory Plan that would explore risk mitigation for those individual elements expected to be in short supply like neodymium and dysprosium.

This plan would be a follow-up to another congressionally mandated report, due to come out this summer, that essentially includes a supply and demand analysis by element for DOD. The Coffman amendment to the FY12 NDAA would require the Defense National Stockpile Center (now renamed Defense Logistics Agency Strategic Materials) to look at the elements in shorter supply and identify how the government plans on securing those elements and downstream value-added products such as metal, alloy and magnets. The amendment would only cover defense applications (not commercial), though the executive branch could take it further, should it so choose, according to Green.

Rather than try broad-brush solutions, Green suggests approving smaller incremental approaches that actually offer solutions. For example, he suggests passage of an initial bill that covers specific rare earth metals as opposed to all or other critical materials such as copper and cobalt that could quickly spin legislative action out of control.

Neodymium, Samarium, Dysprosium, Yttrium, Terbium: Good Places to Start

The “€œheavies”,€ as they are commonly referred to, present a different challenge as the US currently does not produce any of these elements.

Moreover, according to the U.S. Magnetic Materials Association (USMMA), the following defense applications remain dependent upon rare earth materials. In particular, precision-guided munitions (requiring samarium-cobalt or neodymium iron boron permanent magnets), neodymium iron boron magnets used in helicopter stealth technology, tanks and other vehicles use rare earth lasers for range finding, military communication satellites and yttria-stabilized zirconia used in “€œhot”€ sections of jet engines, according to the USMMA.

The USMMA supports legislation that “€œemphasizes production”€ to restart reliable domestic manufacturing for these key materials as well as defense-specific stockpiling for the most critical of the 17 rare earth elements via the Defense Logistics Agency.

At the end of the day, according to Green, US public policy should focus on only two initiatives:

  • Define what we are short of
  • Determine how we get it

It’€™s hard to argue with that. But with some estimates of the time needed to rebuild a rare-earth supply chain of 15 years, and a minimum of two years to create magnet facilities for sintered neodymium iron boron permanent magnets, Congress had better start acting soon.
