As trade tensions rise between the U.S. and China, rare earth minerals are once again in the political spotlight. Today Chinese mines and processing facilities provide most of the world’s supply, and Chinese leader Xi Jinping has hinted about using this as political leverage in trade negotiations with U.S. President Donald Trump’s administration. But in the long run, many experts say the global market involving these materials would likely survive even if China completely stopped exporting them.

The 17 rare earth elements, which cluster near the bottom of the periodic table, play a vital role in several industries: consumer electronics including Apple AirPods and iPhones, green technologies such as General Electric wind turbines and Tesla electric cars, medical tools including Philips Healthcare scanners, and military hardware such as F-35 jet fighters. …….

In the event of a longer Chinese supply interruption, the U.S. rare earths mine at Mountain Pass, Calif., would likely become the first place to step up production, Gholz explains. The mine’s previous owner, Molycorp, spent approximately $1.5 billion building a new separation facility for producing rare earth concentrates. It did not, however, complete the downstream processing needed to produce purified rare earth materials before the company went bankrupt in 2015 because of Chinese competition. The mine’s new owner, MP Materials, plans to reactivate and complete the mothballed facility for fresh operation starting in 2020.

Another alternative is Australian company Lynas Corp., the world’s only significant rare earths producer outside China. It currently operates a mine at Mount Weld in Australia, and sends ores to a separation facility in Malaysia that can purify the rare earth materials—but a complication has arisen from the fact that some ores contain radioactive thorium. Environmental concerns about low-level radioactive waste from the separation facility recently led Lynas to announce it will move some some of the “upstream” processing (which involves the radioactivity) back to Australia, while keeping “downstream” processing in Malaysia.   The company has also announced it will work with Texas-based Blue Line Corp. to build a new separation facility in the U.S. for operations starting in 2022 at the earliest………https://www.scientificamerican.com/article/dont-panic-about-rare-earth-elements/
