US Mining Companies Show New Interest in Rare Earth




The mineral bastnasite can contain 15 or even 17 rare earth metals. But chemically separating the elements is costly and difficult


JIM SIMS: "Molycorp is the western hemisphere's only producer of rare earth products."

EDWARD COWLE: "In these two years since we changed our name to Rare Earths, the media attention has been unbelievable."



JIM SIMS: "Every rare earth deposit on the planet has all fifteen and sometimes all seventeen rare earths."

He says Molycorp raised about three hundred eighty million dollars when it sold stock to the public for the first time in July. The company aims to increase production to twenty thousand tons by two thousand twelve. It says that would more than meet current levels of demand in the United States.


EDWARD COWLE: "I would say conservatively the earliest that we could open the mine has to be six to seven years."

Today we continue our report on the group of chemical elements known as rare earth metals. These are mined from the earth and used to make technology from mobile phones to missiles.


The United States stopped mining rare earths in two thousand two. Companies blamed environmental rules and low-priced imports from China. But now exploration is moving forward again.

The United States once led the world in rare earths. Today China controls almost all production. Premier Wen Jiabao says China will not use these metals as a diplomatic weapon. But Japan says exports meant for that country have remained at Chinese ports as a result of a recent dispute.

This is the VOA Special English Economics Report.

Another American company is Molycorp. Jim Sims, the public affairs director, says Molycorp has already begun producing three thousand tons of rare earths a year. That makes the United States the world's second largest producer, a distant second.


The company has not started mining yet. It still has to get permits and work with other businesses to put operations in place. Ed Cowle says a lot of work remains.


Mr. Cowle later found that the land also held a lot of rare earth metals -- lately a subject of intense interest.

Molycorp says the largest reserves of rare earths outside of China are in its mine in Mountain Pass, California, and in the Mount Weld area of Australia.


And that's the VOA Special English , written by Mario Ritter. I'm Jim Tedder.
