As of 2016, the United States’ demand for rare-earth elements depended on imports, mostly from China. Rare earths are a class of critical minerals, 17 in number, that are used in many technologies such as smartphones, medical treatments, wind turbines and high-performance defense-industry equipment.
Recently, politicians from America’s coal country with the help of researchers, have moved to break that dependency. They hope to re-purpose old mines to produce rare earths, thus stimulating new economic growth in places like West Virginia. But we must learn from China’s example and avoid devastating environmental consequences, which are costing China billions of dollars to correct.
The US uses about 15,000 tonnes of rare-earth elements every year, more than 700 tonnes of which go to defense. West Virginia Democratic Senator Joe Manchin recently told the Washington Examiner that America’s reliance on foreign sources for such a vital material is “a national security concern that must be addressed.”
