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.

2012 Outlook: Uncertainty Continues For Rare Earths Prices, China Still Major Player

(Kitco News) - After exploding onto the metals scene in 2010 and garnering widespread media and investor attention, rare earths element prices have dropped and have been unstable mainly due to demand tapering off in 2011, leading to uncertainty in 2012.

Low demand during 2011 was caused by high rare earths prices from both heavy and light rare earths metals, which despite their fluttering prices, remain historically high.

Despite unstable prices throughout 2011, there is some expectation that rare earths prices might become more stable in 2012.

“I think that rare earth metals, they tend to be more strategic in nature and supply versus demand remains quite balanced in favor of prices being stronger in 2012,” said Mike Frawley, global head of metals at Newedge Group. “The pace of consumption in mainland China is a critical component of demand, prices.”

The Chinese continue to control most of the rare earths supply but reports show that Chinese exports are extremely low. Information provided by Metal Pages, a news site that focuses on non-ferrous metals, ferro alloys and rare earths, indicated that rare earth elements exports have dropped 65% in 2011 and that China has only exported 11,000 metric tons of rare earths through the first three quarters of the year.

Reports suggested that the Chinese government may change regulations that would get around Chinese producers who have cut their supply while keeping prices high.

Rare earths prices alone are also an issue not only with volatility, but with their general cost.

According to a report focused on rare earth elements performance for the upcoming year from A.L. Waters Capital, the firm highlighted some specific rare earths and their current prices compared to their peak prices.

A heavy rare earth such as dysprosium, which is commonly used in televisions and lasers, reached a market high of $2,800 per kilogram while its current price is $2,000.

Another heavy rare earths type, europrium, which is used in television screens, peaked at $5,900/kg while its current price is $3,900.

Some light rare earths come at a substantially cheaper price, such as neodymium, which is used in magnets, peaked at $410/kg on the market and currently sits at $270. (A complete list of all 17 rare earth metals and their uses can be found at the end of the article.)

While rare earths are expensive to use in producing several products used daily, the drop in demand does not come from an alternate substance that can be as effective for a fraction of the cost.

“Demand has gone down (in 2011) but I also think that they haven’t really been able to replace rare earth metals,” said Arnett Waters, chairman of A.L. Waters Capital. “I think that part of what’s going on is that businesses are spending less money on more expensive stuff. If I have a use for europrium and I can use a quarter of a pound of it and it does ok in the product that I’m making, I’m not going to adopt a new product in this economy. It would cost too much money.”

Also, with current economic crises around the globe, it is expected that demand will not be strong in 2012 given the historical high prices of rare earths.

Waters used strategic military defense equipment as an example.

“In the case of strategic military equipment, defense budgets are declining,” Waters said. “I realize the U.S. may not be cutting stealth bomber production, but I am saying that in many countries that would like to use these rare earth metals for strategic purposes are cutting their defense budgets and they cannot afford it.”

Rare earths metals play a large role in current modern technology, cruise missiles and other weapons systems.

PRODUCING RARE EARTHS METALS OUTSIDE OF CHINA

China holds most of the processing capacity for rare earths metals.

“A lot of the processing capacity is in China and you can’t use Chinese capacity unless you’re actually getting your rare earths from them,” said Waters. “That’s why Lynas Corporation Ltd. (ASX: LYC) and others have been building their plants in Malaysia.”

Lynas currently has a concentration plant under construction at Mount Weld in Western Australia as well as an advanced materials plant in Kuantan, Malaysia. Neither plant has begun production yet.

Molycorp Inc. (NYSE:MCP) has three facilities, two located in the U.S., California and Arizona respectively, as well as one located in Estonia. The company stated earlier in 2011 that production from the three facilities would produce between 4,941 and 5,881 metric tons by the end of 2011. The company expects to raise production to 19,050 metric tons by the end of 2012.

The sentiment to mine and produce rare earths outside of China does not fall squarely on the shoulders of these two companies but it is still believed that bigger companies will gain more control of mines and production compared to smaller mining companies.

“At the end of the day it just means that there’ll be fewer smaller mines and there’s a natural evolutionary process that takes place in all developing parts of the world,” said Frawley. “You’ll have the small miners who will be succeeded by stronger companies. A more efficient process will begin to emerge.”

“That takes a long time and I don’t see it changing the balance of that supply any time soon.”

RARE EARTHS AS AN INVESTMENT OPTION FOR THE GENERAL PUBLIC

The biggest obstacle rare earths metals face as an investment is that although classified under the umbrella of rare earths metals, there are 17 different types and they are separated into two categories.

“Rare earth prices are not listed like precious and base metals prices so it is difficult for the average person to invest in,” said Waters. “It’s a barrier to the growth of the industry.

“As the market is maturing, there is going to be a need for a centralized source of information.”

Although newer in the metals world than precious and base metals, information can always be found.

“They’re small markets in comparison to gold, copper and aluminum in terms of tonnage and consumption tonnages,” Frawley said. “In terms of price transparency of these markets you’ll have to dig a little deeper.”

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?

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.

China’s Rare Earths Monopoly - Peril or Opportunity?

September 30, 2011 (Source: Market Oracle) — The prosperity of China’s “authoritarian capitalism” is increasingly rewriting the ground-rules worldwide on the capitalist principles that have dominated the West’s economy for nearly two centuries.

Nowhere is this shadow war more between the two systems more pronounced than in the global arena of production of rare earths elements (REEs), where China currently holds a de facto monopoly, raising concerns from Washington through London to Tokyo about what China might do with its hand across the throat of high-end western technology.

In the capitalist West, as so convincingly dissected by Karl Marx, such a commanding position is a supreme and unique opportunity to squeeze the markets to maximize profits.

Except China apparently has a different agenda, poking yet another hole in Marx’s ironclad dictums about capitalism and monopolies, further refined by Lenin’s screeds after his Bolsheviks inadvertently acceded to power in 1917 in the debacle of Russia’s disastrous involvement in World War One. Far from squeezing its degenerate capitalist customers for maximum profit (and it’s relevant here to call Lenin’s dictum that if you want to hang a capitalist, he’ll sell you the rope to do it), Beijing has apparently adopted a “soft landing” approach on rare earths production, gradually constricting supplies whilst inveigling Western (and particularly Japanese) high tech companies to relocate production lines to China to ensure continued access to the essential commodities.

REEs are found in everyday products, from laptops to iPods to flat screen televisions and hybrid cars, which use more than 20 pounds of REEs per car. Other RRE uses include phosphors in television displays, PDAs, lasers, green engine technology, fiber optics, magnets, catalytic converters, fluorescent lamps, rechargeable batteries, magnetic refrigeration, wind turbines, and, of most interest to the Pentagon, strategic military weaponry, including cruise missiles.

Technology transfer is the essential overlooked component in China’s economic rise, and Beijing played Western greed on the subject like a Stradivarius, promising future access to China’s massive market in return, an opium dream that rarely occurred for most companies. You want unimpeded access to Chinese RREs? Fine – relocate a portion on your production lines here, or…

Which brings us back to today’s topic.

Rare earths and investment – where to go?

China is riding a profitable wave, which depending on what figures you read, produces 95-97 percent of current global supply, and unprocessed raw earth earths ores are currently going for more than $100,000 a ton, or $50 a pound, which some of the exotica fetching far more (niobium prices has increase an astounding 1,000 percent over the last year). Rare earth elements like dysprosium, terbium and europium come mainly from southern China.

According to a United States Energy Department report, dysprosium, crucial for clean energy products rose to $132 a pound in 2010 from $6.50 a pound in 2003.

The soaring prices however have also invigorated many countries and producers to begin looking in their own back yards, for both new deposits and former mining sites that were shuttered when production cost made them uneconomic before prices went through the ceiling.

However, a number of unknown factors play into developing alternative sources to current Chinese RRE production. These include first prospecting possible sites, secondly, their purity and third, initial production costs, where modest Chinese labor costs are a clear factor.

The 17 RRE elements on the Periodic Table are actually not rare, with the two least abundant of the group 200 times more abundant than gold. They are, however, hard to find in large enough concentrations to support costs of extraction, and are frequently found in conjunction with radioactive thorium, leading to significant waste problems.

At hearings last week before U.S. House of Representatives Committee on Foreign Affairs Subcommittee on Asia and the Pacific, Molycorp, Inc. President and Chief Executive Officer Mark A. Smith stated that his company was positioned to fulfill American rare earth needs, currently estimated at 15,000-18,000 tons per year, by the end of 2012 if it can ramp up production at its Mountain Pass, California facility.

Which brings us back to foreign producers. A year ago Molycorp announced that it was reopening its former RRE mine in Mountain Pass, Calif., which years ago used to be the world’s main mine for rare earth elements, filing with the SEC for an initial public offering to help raise the nearly $500 million needed to reopen and expand the mine. Low prices caused by Chinese competition caused the Mountain Pass mine to be shuttered in 2002.

Mountain Pass was discovered in 1949 by uranium prospectors who noticed radioactivity and its output dominated rare earth element production through the 1980s; Mountain Pass Europium made the world’s first color televisions possible.

Molycorp plans to increase its capacity to mine and refine neodymium for rare earth magnets, which are extremely lightweight and are used in many high-tech applications and intends to resume production of lower-value rare earth elements like cerium, used in industrial processes like polishing glass and water filtration.

In one of those historic economic ironies, China was able to increase its RRE production in the 1980s by initially hiring American advisers who formerly worked at Mountain Pass.

The record-high REE prices are also underwriting exploration activities worldwide by more than six dozen other companies in the United States, Canada, South Africa, Malaysia and Central Asia to open new RRE mines, but with each start-up typically raising $10 million to $30 million, not all will succeed. That said, the future is bright, as almost two-thirds of the world’s supply of REEs exists outside of China and accordingly, China’s current monopoly of REE production will not last.

So where do investors look to cash in on the RRE boom?

First, do your homework.

Exhibit A is Moylcorp, which would seem to be in unassailable position as regards U.S. production, but which nevertheless on 20 September after JPMorgan Chase & Co. lowered its rating of the company, citing declines in rare-earth prices, causing its stock to plummet 22 percent in New York Stock Exchange composite trading, despite being the best-performing U.S. IPO in 2010 after beginning trading in July, more than tripling after rare-earth prices soared as China cut export quotas.

Is there money to be made in RREs?

Undoubtedly – but the homework for the canny investor needs to extend beyond spreadsheets to geopolitics, mining lore, chemistry and Wall Street puffery. That said, it seems likely that whatever U.S.-based company can cover the Pentagon’s RRE requirements is likely to see more than a minor boost in its bottom line.

Gentlemen, place your bets – but do your homework first.

China Consolidates Grip on Rare Earths

BEIJING€” In the name of fighting pollution, China has sent the price of compact fluorescent light bulbs soaring in the United States.

The price of compact fluorescent light bulbs has risen drastically in the last year because of the rising cost of rare earth metals.
Add to Portfolio

By closing or nationalizing dozens of the producers of rare earth metals — which are used in energy-efficient bulbs and many other green-energy products — China is temporarily shutting down most of the industry and crimping the global supply of the vital resources.

China produces nearly 95 percent of the world’s rare earth materials, and it is taking the steps to improve pollution controls in a notoriously toxic mining and processing industry. But the moves also have potential international trade implications and have started yet another round of price increases for rare earths, which are vital for green-energy products including giant wind turbines, hybrid gasoline-electric cars and compact fluorescent bulbs.

General Electric, facing complaints in the United States about rising prices for its compact fluorescent bulbs, recently noted in a statement that if the rate of inflation over the last 12 months on the rare earth element europium oxide had been applied to a $2 cup of coffee, that coffee would now cost $24.55.

A pack of three 11-watt G.E. compact fluorescent bulbs each the lighting equivalent of a 40-watt incandescent bulb€” was priced on Thursday at $15.88 on Wal-Mart’€™s Web site for pickup in a Nashville, Ark., store. The average price for fluorescent bulbs has risen 37 percent this year, according to the National Electrical Manufacturers Association.

Wal-Mart, which has made a big push for compact fluorescent bulbs, acknowledged that it needed to raise prices on some brands lately. €œObviously we don’t want to pass along price increases to our customers, but occasionally market conditions require it, Tara Raddohl, a spokeswoman, said. The Chinese actions on rare earths were a prime topic of conversation at a conference here on Thursday that was organized by Metal-Pages, an industry data firm based in London.

Soaring prices are rippling through a long list of industries.

The high cost of rare earths is having a significant chilling effect on wind turbine and electric motor production in spite of offsetting government subsidies for green tech products, said one of the conference attendees, Michael N. Silver, chairman and chief executive of American Elements, a chemical company based in Los Angeles. It supplies rare earths and other high-tech materials to businesses.

But with light bulbs, especially, the timing of the latest price increases is politically awkward for the lighting industry and for environmentalists who backed a shift to energy-efficient lighting.

In January, legislation that President George W. Bush signed into law in 2007 will begin phasing out traditional incandescent bulbs in favor of spiral compact fluorescent bulbs and other technologies. The European Union has also mandated a switch from incandescent bulbs to energy-efficient lighting.

Representative Michele Bachmann of Minnesota is running for the Republican presidential nomination on a platform that includes strong opposition to the new lighting rules in the United States and has been a leader of efforts by House Republicans to repeal it.

China says it has largely shut down its rare earth industry for three months to address pollution problems. By invoking environmental concerns, China could potentially try to circumvent international trade rules that are supposed to prohibit export restrictions of vital materials.

In July, the European Union said in a statement on rare earth policy that the organization supported efforts to protect the environment, but that discrimination against foreign buyers of rare earths was not allowed under World Trade Organization rules.

China has been imposing tariffs and quotas on its rare earth exports for several years, curtailing global supplies and forcing prices to rise eightfold to fortyfold during that period for the various 17 rare earth elements.

Even before this latest move by China, the United States and the European Union were preparing to file a case at the W.T.O. this winter that would challenge Chinese export taxes and export quotas on rare earths.

Chinese officials here at the conference said the government was worried about polluted water, polluted air and radioactive residues from the rare earth industry, particularly among many small and private companies, some of which operate without the proper licenses. While rare earths themselves are not radioactive, they are always found in ore containing radioactive thorium and require careful handling and processing to avoid contaminating the environment.

Most of the country’€™s rare earth factories have been closed since early August, including those under government control, to allow for installation of pollution control equipment that must be in place by Oct. 1, executives and regulators said.

The government is determined to clean up the industry, said Xu Xu, chairman of the China Chamber of Commerce of Metals, Minerals and Chemicals Importers and Exporters, a government-controlled group that oversees the rare earth industry. €œThe entrepreneurs don’€™t care about environmental problems, don’t care about labor problems and don’€™t care about their social responsibility,€ he said. €œAnd now we have to educate them.

Beijing authorities are creating a single government-controlled monopoly, Bao Gang Rare Earth, to mine and process ore in northern China, the region that accounts for two-thirds of China’s output. The government is ordering 31 mostly private rare earth processing companies to close this year in that region and is forcing four other companies into mergers with Bao Gang, said Li Zhong, the vice general manager of Bao Gang Rare Earth.

The government also plans to consolidate 80 percent of the production from southern China, which produces the rest of China’€™s rare earths, into three companies within the next year or two, Mr. Li said. All three of these companies are former ministries of the Chinese government that were spun out as corporations, and the central government still owns most of the shares.

The taxes and quotas China had in place to restrict rare earth exports caused many companies to move their factories to China from the United States and Europe so that they could secure a reliable and inexpensive source of raw materials.

China promised when it joined the W.T.O. in 2001 that it would not restrict exports except for a handful of obscure materials. Rare earths were not among the exceptions.

But even if the W.T.O. orders China to dismantle its export tariffs and quotas, the industry consolidation now under way could enable China to retain tight control over exports and continue to put pressure on foreign companies to relocate to China.

The four state-owned companies might limit sales to foreign buyers, a tactic that would be hard to address through the W.T.O., Western trade officials said.

Hedge funds and other speculators have been buying and hoarding rare earths this year, with prices rising particularly quickly through early August, and dipping since then as some have sold their inventories to take profits, said Constantine Karayannopoulos, the chief executive of Neo Material Technologies, a Canadian company that is one of the largest processors in China of raw rare earths.

“€œThe real hot money got into the industry building neodymium and europium inventories in Shanghai warehouses,”€ he said.

Correction: September 17, 2011
An article on Friday about the effect of China’s control over rare earth metals on energy-efficient products like light bulbs misstated the price of 11-watt G.E. compact fluorescent bulbs listed on Wal-Mart’€™s Web site. The price of $15.88 is for a three-pack, not a single bulb.

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.

How electronics boom is creating surge in demand for rare metals

Everything from iPods to Toyota Priuses to wind turbines are made using rare metals.
By Andy Bloxham 7:45AM GMT 11 Feb 2011

For example, the silver-grey metal tantalum is used in mobiles as a powder which helps regulate voltage, which would otherwise drop as temperatures rose. Its abilities have been vital to reducing the size of mobiles.

Hafnium is a key ingredient of Intel’s computer chips.

However, China produces around 97% of the world’s supplies, much of it coming from small mines operated by criminal gangs.

In the middle of last year, when the world market for rare earths was only £870m a year, China capped production levels and imposed a moratorium on all new mining licences until June this year.

Then, in December, it cut exports of the metals by over a third, prompting protests from Japan and the US.

With demand for iPhones and iPods soaring (Apple sold a total of 23m of the gadgets in the last three months of 2010 alone) and China keeping a tight rein on supply, the price is only likely to rise strongly.

So-called “rare earth” metals are named as such because when mining boomed in the 18th century, they were particularly hard to extract.

There are 17 of them but they are necessary building materials for navigation systems, radar, night vision goggles and, more importantly, mobile phones.

They include cerium (symbolised by Ce), lanthanum (La), neodymium (Nd), dysprosium (Dy), terbium (Tb) and europium (Eu).

U.S. at risk of rare earths supply disruptions

The United States risks major supply disruptions of rare earth metals used in clean energy products unless it diversifies its sources of the minerals, the Energy Department warns in a report due to be released later on Wednesday.

The United States and other countries are worried that China, which controls 97 percent of the world trade in rare earth metals, will use those supplies as a political weapon and cut back their export when it is in a dispute with another country or to grow China’s clean energy technology sector.

“The availability of a number of these materials is at risk due to their location, vulnerability to supply disruptions and lack of suitable substitutes,” U.S. Energy Secretary Steven Chu said in a report, due to be unveiled on Wednesday at a rare earth metals conference at the Center for Strategic and International Studies.

The release of the report coincides with trade talks in Washington between the United States and China. U.S. officials are expected to push Chinese officials to loosen export restraints on rare earth elements.

China, which said on Tuesday it planned to raise export taxes on some rare earth metals beginning next month, holds 37 percent of known rare metal reserves, the United States has 13 percent and the rest is in other countries.

The 17 rare earth metals, with exotic names like lanthanum and europium, form unusually strong lightweight materials and are used in a wide range of applications including high-tech and defense products, car engines and clean energy.
