The Challenges of Restarting U.S. Rare Earth Metal Production


Rare earth metals go into all kinds of advanced electronics from components of Abrams tanks to wind turbines. While the U.S. once dominated the production of the minerals, 95 percent of the supply now comes from China. In recent weeks, what The New York Times has described as an "embargo on shipments" of the metals out of China has highlighted the insecurity of that supply. Others have suggested a variety of other reasons for the lack of rare earth exports that don't pack the geopolitical punch of an unannounced embargo.

Either way, the fact remains that China controls almost all the supply of a key raw material, and the US is going to have a hell of a time trying to muscle the country's leaders into doing anything they don't want to with them.

One way to solve the problem would be to support domestic rare earth metal production. But that's not going to be easy. While the mine that long produced metals still exists out in California, and there's a company (Molycorp) that wants to get it running, it may not be the cheapest possible way of producing rare earths. But perhaps more crucially, we're missing key expertise because we let the knowledgeable people wander away from the industry when it collapsed. (I'll just note that the same thing has hampered much energy research since the 1970s.)

All that to say: read the New York Times' Room for Debate discussion about rare earths. You'll get a nice, round vision of what'd be needed to get just this one small industry up and running:

But China's recent embargo on shipments on the crucial minerals to the United States, Europe and Japan raised new concerns about Beijing's monopoly, and added urgency to efforts by other countries to develop their own source of the minerals, for which demand is growing.

Molycorp Minerals, the operator of the Mountain Pass site, wants to reopen the mine with higher safety and environmental standards. In Australia, a mining company, Lynas Corporation, hopes to begin small-scale production at a rich deposit in the middle of the country, though technical issues remain.

But even if the U.S. and other countries can find and unearth the elements, do they have the technical expertise to compete with China in their processing? Is the domestic production of rare earth elements essential to American economic and national security interests?
