Scarce rare-earth ores are a set of 17 featuring scandium, yttrium, the 15 lanthanides ranging from lanthanum to lutetium, occurring together in many ore sources and critical for magnets, catalysts, as well as clean-energy tech. Cerium the most plentiful REE in the crust, whereas promethium does not occur naturally and has radioactive isotopes. Worldwide supply lines have historically depended on a limited number of countries for mining and processing, prompting ongoing diversification efforts amid price volatility due to factors like mining, processing, and geopolitics. American Molycorp began production at Mountain Pass and aims for full capacity to reach 19,050 metric tons, with a separation plant at Mountain to processing. Rare earth elements are found in catalysts and magnets in modern tech, driving clean-energy applications and advanced manufacturing. Their worldwide significance has prompted diversification and supply chain reforms to reduce price swings from mining, processing, and geopolitical factors. Overall, rare-earth elements continue to be vital for modern technology in green energy advancement.
Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through lutetium [Lu]).

Molycorp also operates a separation plant at Mountain Pass, CA, and sells rare earth concentrates and refined products from newly mined and previously mined above-ground stocks. Molycorp announced its purchase of Neo Materials
