Compounding the difficulties of separation were a lack of good methods for identification and assessment of purity and a lack of knowledge of the number of rare earth elements that existed. The first rare earth element, yttrium, was isolated in 1794 by the Swedish chemist Johan Gadolin from a heavy black mineral, ytterbite, named for the ...

Oct 17, 2017 “Rare earth elements occur in ores in very small concentrations, a few thousand parts per million. Extensive processes of mining, grinding, extraction, and purification are needed to transform the ores to very high purity (approximately 99.9 percent minimum) rare earth metals required for commercial applications,” she said.
