Japan and the U.S. are by far the largest importers, collectively accounting for more than two-thirds of China's rare earth metals exports. Lanthanum, found in hybrid vehicles and smartphones, was China's largest rare earth export by volume, followed by cerium.In dollar terms, terbium was the most expensive—generating $57.9 million from just 115 metric tons of exports.

taining U, TRUs, rare earth elements (REs) and alkaline earth metals. In this step, U and TRUs are preferentially extracted into the Bi phase, and are separated from the REs by the difference in distribution coefficients between liquid LiCl-KCl and Bi. In the spent salt treatment step, alkaline earth metals and REs are recovered into a lead ...
