By the late 1980s, China was intensively mining its own rare earths - and selling them at lower prices. During the mid-20th century, rare earth elements were becoming useful in a variety of ways: Cerium, for example, was the basis for a glass-polishing powder and europium lent luminescence to recently invented color television screens and fluorescent lamps.įor the next few decades, the site, later dubbed Mountain Pass mine, was the world’s top source for rare earth elements, until two pressures became too much. The company was interested in mining the rare earths. Traces of radioactive thorium, also in the ore, had set the Geiger counters pinging.Īs disappointing as that must have been, the bastnaesite still held value, and the prospectors sold their claim to the Molybdenum Corporation of America, later called Molycorp. But instead of uranium, the brownish-red stuff turned out to be bastnaesite, a mineral bearing fluorine, carbon and 17 curious elements known collectively as rare earths. Their instruments detected intense radioactivity in brownish-red veins of ore exposed in a rocky outcrop within California’s Clark Mountain Range.
