Rare Element on Earth Discovered in Ancient Starlight

Light from three ancient stars at the edge of the Milky Way indicates that the stars contain tellurium, a brittle, superconducting element that is rare on Earth.

The cosmic discovery, which also spotted traces of other heavy elements, supports the theory that these elements were synthesized in the rapidly collapsing cores of rare supernovas (stellar explosions).

“You can make iron and nickel in any ordinary supernova, anywhere in the universe,” said Anna Frebel, an astrophysicist at the Massachusetts Institute of Technology and a member of the research team. “But these heavy elements seem to only be made in specialized supernovas.”

According to the theory, heavy atoms form during rapid nuclear fusion at the heart of some supernovas. Called r-process, it sets in when a supernova core collapses, bombarding atomic nuclei with a fierce onslaught of neutrons. The result is the production of atoms heavier than iron, which then get hurled into space, enriching the cloud of gas and dust that eventually collapses to form another star.

And if the theory is right, some of those atoms ought to end up in stars like those analyzed by Frebel and the rest of her team. [Supernova Photos from Star Explosions]

To analyze the chemical composition of the three stars at the Milky Way’s edge, the researchers studied data gathered by the Hubble Space Telescope’s spectrograph, an instrument that splits incoming starlight into a spectrum of wavelengths. If an element is present in a star, the atoms of that element absorb starlight at specific wavelengths, leaving telltale dips in signal in the spectrograph’s data.

The scientists detected dips in the ultraviolet region of the spectrum at a wavelength that matched tellurium’s light absorption, signifying the presence of the rare element in the 12-billion-year-old stars. Furthermore, the abundance of tellurium relative to that of other heavy elements, such as barium and strontium, was the same in all three stars. According to Frebel, the matching ratios support the theory that a rare type of supernova may have created the elements in the bottom half of the periodic table, including tellurium.

The finding helps flesh out one chapter in the cosmic history of the elements, an ongoing effort of astronomers and nuclear physicists to understand the formation of the 94 naturally occurring types of matter.

According to Jennifer Johnson, an associate professor of astronomy at Ohio State University who was not involved in the new research, tellurium has been a “tough” element to detect because it absorbs light in the ultraviolet spectrum. UV signals tend to be flooded by sunlight and are impossible for ground-based telescopes to spot.

“If you look at the periodic table, tellurium is right in the middle of these elements that are hard for us to measure,” Johnson said in a statement. “If we need to understand how [the r-process] works in the universe, we really have to measure this part of the periodic table. It’s really cool that they got this element in this sea of unknown-ness.”

Frebel and her colleagues are attempting to fill in other spots in the periodic table, too, by looking for signs of other heavy elements in starlight. “There are still quite a few holes,” she said. “Every now and then, we can add an element, and it adds another data point that makes our work easier.”

The researchers have published their findings online in Astrophysical Journal Letters.

Critical Metals Vital to Our Lives in Tight Supply

">

Rare Earth Elements

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?

Endangered Elements: Tungsten Among China’s Potential Embargo List

">

Rare Industrial Metal - Tungsten / Wolfram

It didn’t take long for the panic to set in, last year, when the Chinese government flexed its muscle by threatening the world’s Rare Earth Element (REE) supply. With 95% of REE supplies coming from China, that scare was indeed legitimate. But REEs aren’t the only elements with which China has the potential to choke off. On American Elements’ 2011 Top 5 US Endangered Elements List, three elements (tungsten, indium and neodymium) have over 50% of world supply coming from Chinese mines.

To refresh the memory of those who followed the rare earth surge from last year, and the subsequent piquing of interest in rare earth companies, it began with Japan. As the summer of 2010 was coming to a close, reports of an embargo of shipments to Japan for REEs raised concern for manufacturers who depend upon the elements for production primarily in the tech industry. Within a month, that embargo spread to North America and Europe, and concern over Chinese monopolization rose, along with REE prices, and those of the companies devoted to them. When the embargo ended, relief came to the sector, while the pace of development outside of China received only a minor increase. The threat of supply shortages still lingers, especially with tungsten, indium and neodymium.

The example of tungsten is not to be ignored, as 85% of global production comes from China, which has already indicated it might end all exports altogether due to domestic demand increases. With the highest melting point and greatest tensile strength of all elements, tungsten’s importance is unquestionable. Used in all situations that call for high temperature thresholds or hardness and strength, tungsten is imperative to many modern living standards that depend upon it. From a US perspective, the element’s use in the aerospace program, electronics and military (including in bullets and armor) is critical. To the mining industry as a whole, tungsten is a savior with many uses within the assembly of mining equipment itself, including drills in need of durability. Strangely enough, the United States dismantled domestic production of tungsten ore in 1994 with the last tungsten mine, the Pine Creek Mine in Inoyo, California, going down as a historical footnote en route to Chinese dependence.

Today, tungsten production remains primarily within China, but awareness of a need to develop outside of the PRC is becoming clearer. Options in the western hemisphere are appearing, and may soon be getting the attention they need to aid this drive for domestic independence. Juniors such as North American Tungsten [NTC - TSX.V] and Playfair Mining [PLY - TSX.V] may provide answers that mitigate a possible future supply breakdown. For North American Tungsten, the title of being the western world’s leader in tungsten production doesn’t come lightly. Through developing its Cantung Mine, it provides tungsten concentrate production within the borders of Canada’s Northwest Territories, which from an international standpoint is a much more secure mining investment environment to work within. At a much earlier stage, Playfair Mining is not yet a producer, but is heavily leveraged to the price of tungsten, which today sits around $440/MTU (“metric tonne unit”) or over $20/lb. With a goal in mind to partner with an end user of tungsten metal in order to finance its Grey River deposit into production, Playfair is well aware of the potential impact a tungsten shortage would carry.

Due to its high level of use in the manufacturing sector, a significant number of Fortune 500 companies are dependant upon tungsten’s availability. General Electric and its Tungsten Products Division, along with others like Kennametal and ATI Firth Sterling are among those that would most likely benefit from securing a long term tungsten supply, and are among potential targets should Playfair seek a high-worth partner to put its nearest term tungsten property into production. The company has 4 high-grade deposits with two located in the Yukon, one in the Northwest Territories and another on the southern coast of Newfoundland. Each of the properties was acquired strategically during a period of massively deflated tungsten prices, prior to this latest surge over the $440/MTU mark. This increase represents a 70% rise from the recent low prices that graced Playfair’s entry period. While the commodity’s price has risen, the company’s stock has yet to follow suit.

While the current price of the stock seems to have languished, the team is making strides to be better prepared for when the bigger end-users in need of tungsten come knocking. The board includes experienced individuals who have taken deals into production before, as well as Director James Robertson who took the last big tungsten company outside of China to successful acquisition. In both combined 43-101 compliant and non-compliant resource categories, Playfair’s tungsten properties contain more than an estimated 5.5 million MTUs of WO3. It’s to be expected, though, that since Playfair is an exploration company, these resources have room for expansion. As economic uncertainty lingers in all global markets, crucial and endangered elements such as REEs, tungsten, indium and neodymium will be within the watchful eye of western manufacturers in need of these ingredients for their operations. Whether another anticipated panic is inflicted by possible impending embargo actions by China doesn’t change the dependence we have on endangered elements. And like last year’s REE crisis, a price surge on those companies were set to move prior complications is entirely a likely scenario. G. Joel ChuryProspectingJournal.com

Critical Reading for Rare Earth Metals Investors

Rare Earth Element - Yttrium

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.
