What are the rare earths? The lanthanide or rare earth metals include lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. scandium and yttrium are also sometimes included in this group in that they share many properties. They appear much like the transition metals, silvery metallic, and find many similar applications. Lanthanum and cerium are used in many solar energy, alloying, electronic, glass, fuel cell, nanotechnology and ceramic applications. Neodymium, praseodymium, erbium and dysprosium ions emit and absorb wave lengths within the visual light range making them useful in applications as varied as welding goggles to fiber optics to medical lasers. Promethium is the one lanthanide that does not naturally occur. Safety Information, properties and technical data for each of the rare earth elements and their many forms are provided.

How are rare earths produced? The 14 elements that make up the rare earth or lanthanide series are produced through the separation of certain rare earth oxide bearing minerals, including Bastnazite, Monazite and Ionic Clays. Mined Bastnazite is processed to a rare earth concentrate which is separated by solvent extraction into individual rare earth chlorides or nitrates depending on the system. These rare earth chloride or nitrate concentrates are subsequently refined to a variety of rare earth compounds, such as oxides, carbonates and fluorides. Rare Earth metal is produced through the thermic reduction of that element's oxide or fluoride powder. 

What are the global locations of rare earths deposits? Essentially the entire world's producing reserves of rare earth minerals is located in Northern and Southern China where American Elements operates a rare earth separations plant. In China, an oft quoted statement of Deng Xiaoping is that "the Middle East has oil and Baotou has rare earths" In fact, 80% of Chinese production is concentrated in Northern China (Baotou, Inner Mongolia). Proven Bastnazite reserves are estimated to be 48 million metric tons with prospective reserves estimated to be another 120 million metric tons. 

Annual Chinese rare earth oxide production presently stands at between 70,000-90,000 metric tons, so the availability of rare earth supplies, from the standpoint of rare earth reserves, is not an issue. However recent changes in limitations placed by the Chinese government on rare earth production and export will limit their availability in the future.

Production quality has also benefited from China's proximity to Japan, a major innovator in rare earth applications in the electronics and automotive industries. As stated, China has two production regions. In the north, "ceric" or "light rare earths" are produced from Bastnazite resources from Baotou. In the south, "yttric" or "heavy rare earths" are mined from ion adsorption clays located in the provinces of Jiangxi and Guangdong.

Additionally, globally outside of China there are a few rare earth sources including Bastnazite (USA), monazite (Australia, India and South Africa), ioparite and apatite (Kazakhstan, Uzbekistan and Ukraine) and ion adsorption clays (Southern China). As described below, most of these regions are not exploiting their reserves. For example, we estimate that current world neodymium oxide production as a percentage basis is as follows:

 
REGION % OF GLOBAL PRODUCTION
China 86%
Russia and Former USSR States 8%
India 4%
Other 2%

 

Australia has monozite deposits in Western Australia as a bi-product of their zirconium and titanium production from heavy mineral sands. In the early 1990's Australia produced a substantial quantity of monozite for export to rare earth separation plants in Asia and Europe. However, production essentially stopped in 1994 due to the problems associated with the disposal of radioactive thorium (a monozite bi-product). There have been several proposals to develop deposits in Western Australia, such as the Mt. Weld deposit in Pinjarra. There are currently not any large commercial producers in Australia.

Brazil also has large monozite deposits in beach sands on the northeast coast of the country. Brazil has several facilities that produce relatively small quantities of separated rare earths. Since 1997, there has been a plan to separate rare earths from a stockpile of monozite at Industrias Nucleares do Brasil's former mining and milling complex with the intent to store the extracted thorium as fuel for nuclear power plants. There are no current large commercial producers in Brazil.

India is currently the largest monozite producer from beach sands along the coast of Kerala and Tamil Nadu. Producers export monozite concentrate, mixed rare earth chlorides and oxides. 

Russia. Several small rare earth processing facilities exist in Russia which process from loparite and apatite deposits in Kazakstan, Uzebekistan and Ukraine. Operations are sporadic and production is usually available only on a spot sale basis. 

South Africa has been planning since 1998 to start up production of monozite from the Steenkampskaal mine in the Western Cape province. Estimated reserves are 250,000 metric tons.

United States. Until 1998, the United States was the second largest producer of rare earths from the Molycorp mine in Mountain Pass, California. The facility was closed in December 1998 due to certain environmental concerns. Several monozite deposits were mined in the past in Florida. These operations were forced to close due to the high cost associated with disposing of the radioactive thorium waste products.

American Elements' Rare Earth Production.  American Elements maintains the world's largest catalogue of rare earth materials, including metals, compounds, nanoparticles and ultra high purity forms. American Elements' Chinese production facility is one of only a few major rare earth separations plants in Baotou with warehouse and shipping facilities at the port in Tianjin. The facility produces under ISO 9002 certification.

As a major Baotou-based producer, American Elements maintains close working relationships with the key city, state and national Chinese government officials controlling both mineral availability and separated rare earth exportation. Our quota allocation is timely granted and more than sufficient to allow for required sales. We will often have early information on the intentions of government officials and some limited ability to provide input in these areas. By producing close to the mineral source, transportation costs are minimized.

Rare Earth History and Historical Pricing. The history of rare earth use in industry began in the 1950's with the invention of the television which required europium as the phosphor. In the 1960's discoveries were made which created applications for the two rare earth elements that make up over 50% of the Bastnazite ore body; cerium and lanthanum. These elements found uses primarily in glass production and production of various catalysts.

The rare earths began to achieve global commoditized pricing in 1987 when large scale prices were first established as a result of the initial commercialization of the NdFeB magnet. Prices steadily rose until around Q2 1989. Stimulated by these relatively high prices and forecasts of 100%+ annual growth, Chinese rare earth separation plants rapidly expanded output capacity resulting in over capacity and price declines through 1992, which was also influenced by a concurrent recession in the global computer market. By Q4 1992 a combination of (1) plants closing that could not compete in this market environment and (2) exponential growth in NdFeB alloy demand, caused a supply shortage. Prices again recovered, steadily rising from Q1 1993 through Q1 1996. However, as early as the end of 1994, Chinese rare earth producers again rapidly increased capacity with, in our estimate, supply actually exceeding demand as early as Q3 1995. 

As prices began to again fall at the beginning of 1996, an effort was initiated by Chinese government agencies to cause producers to voluntarily reduce production to within the projected demand with the stated goal of Chinese officials to establish a continuing "reasonable price" range. This voluntary program was under the threat that China would take a direct hand to control production output and exportation, if voluntary measures were insufficient. However, prices continued to fall through Q3 1999 when Chinese officials announced that export licenses would soon be required for all rare earth product exports. First to respond to this was Japanese buyers who purchased substantial inventories commencing Q4 1999 causing prices to steadily increase.

Prices were additionally impacted by the 1999 closure of the only large scale rare earth mine outside of China; the Mountain Pass mine owned by Molycorp (see above).

In Q2 of 2000, China in fact implemented its export license system granting each producer and certain Chinese import/export companies with quarterly export quota limits based somewhat arbitrarily on a combination of historical volume and a government desire to close many small facilities and reduce the number of ionic clay processors in Southern China in favor of production from Baotou. Additionally, China ordered a production stoppage at many ionic clay mines in Southern China, such that now substantially all rare earth mineral supplies for both exportation and domestic consumption come from Baotou

Current and Projected Rare Earth Trends and Pricing. The forgoing efforts by China to increase and stabilize rare earth prices had only marginal effect. The desire of the central government to continue to collect U.S. currency acted as a countervailing balance. However, in 2005 China first indicated that it was placing a greater emphasize on retaining its raw material resources than continuing to build its cash reserves. This lead to a serious effort to restrict rare earth exports and thereby increase prices.

In 2006, the government issued its first of currently two 10% export tariffs on rare earths. A third 10% tariff is expected before the end of 2007. Additionally, it began to strict the amount of quarterly export quota granted to producers to a very small percentage of the quotas first issued in 2005. In 2008, these factors are expected to force rare earth prices even higher with lower grade forms potentially becoming scarce further in the future.
