The REE (Rare Earth Elements)

Sponsored Post:
Rare earth metals and alloys that contain them are used in many devices that people use every day such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, magnets, fluorescent lighting, and much more. During the past twenty years, there has been an explosion in desire for many items that require rare earth metals. Twenty years ago very few people owned a mobile phone, but today over 5 billion people own a mobile device. The use of rare earth elements in computers has progressed almost as fast as cell phones.

Many rechargeable batteries are made with rare earth compounds. The need for batteries is being driven by desire for portable electronic devices such as cell phones, readers, portable computers, and cameras. Several pounds of rare earth compounds are in batteries that power every electric vehicle and hybrid-electric vehicle. As concerns for energy independence, climate change, and other issues drive the procurement of electric and hybrid vehicles, the desire for batteries made with rare earth compounds might develop even faster.

The rare-earth is fairly abundant, but their availability is somewhat limited, primarily because their concentration levels in many ores are quite low (less than 5 percent by weight). An economically viable source could contain more than 5 percent rare earth unless they are mined with another product — e.g., zirconium, uranium, or iron — which allows economic recovery of ore bodies with concentrations of as little as 0.5 percent by weight.

Of the 83 naturally occurring elements, the 16 naturally occurring rare-earth elements come into the 50th percentile of the elemental abundances. Promethium, which is radioactive, with the major stable isotope having a half-life of around 17.7 years, is not considered to be naturally occurring, although trace amounts have been found in some radioactive ores. Cerium, which is the major abundant, ranks 28th, and thulium, the least abundant, ranks 63rd. Collectively, the rare earth ranks as the 22nd most abundant “element” (at the 68th percentile mark). The non-lanthanide rare-earth elements, yttrium, and scandium are 29th and 44th, respectively, in their abundances.

Rare-earth ore deposits are found all over the world. The major ores are in China, the United States, Australia, and Russia, while other viable ore bodies are found in Canada, India, South Africa, and southeast Asia. The major minerals contained in these ore bodies are bastnasite (fluorocarbonate), monazite (phosphate), loparite [(R,Na,Sr,Ca)(Ti,Nb,Ta,Fe3+)O3], and laterite clays (SiO2, Al2O3, and Fe2O3).
