Rare Earth Elements

Much talk, press and political pressure has occurred recently over the rare earth elements (metals). What are they? Are they really rare? Why all the fuss?

Rare earth elements are seventeen chemical elements (metals) in the periodic table. They are pure elements like copper (Cu), gold (Au), iron (Fe), etc. The names of these rare earth elements/metals are Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pr), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb), Lutetium (Lu) as well as Scandium (Sc) and Yttrium (Y).

These elements are not rare, but because of geology they are dispersed and finding aggregated deposits in mineable quantities is difficult. For many reasons, China now produces 97% of the world's mineable supply of rare earth metals. Yes, it could be said they have a monopoly.

I, Dr. Jerner, started doing research into the properties of the Lanthanide series (all but Scanduim (Se) and Yttruim (Y). The project was a secret (although not TOP SECRET) for the United States Navy. The goal was to see if any of the rare earth and/or rare earth beryllide compounds could be used as thermionic emitters in a nuclear submarine. Quite esoteric at the time.

Today, if not for rare earths, your cell phone would be about the size of a shoe box and your lap top would weight about 20 pounds. There are numerous other applications from loudspeakers, hard drives and neodymium magnets that rely on rare earth metals. The price of some of the rare earth metals has soared 500-800% just this year.

The monopoly that China now holds will be broken or at least much alleviated by 2012-2015. New and old mines will soon be opened and reopened and rare earths will become more readily available.
