Rare earth elements remain a set of 17 including scandium, yttrium, the 15 lanthanides ranging from lanthanum to lutetium, found together in numerous ore sources that are critical for magnets, catalysts, and clean-energy tech. Cerium the most plentiful REE in the crust, whereas promethium is not naturally occurring and is radioactive. Worldwide supply lines have historically depended on a limited number of countries for mining and processing, prompting continuous diversification efforts and price volatility due to mining, processing, and geopolitical factors. U.S.-based Molycorp began production at Mountain Pass and targets full capacity in 2014, with a separation plant at Mountain for processing. Rare earth elements are found in catalysts and magnets across modern technology, supporting clean-energy applications and advanced manufacturing. Their worldwide significance has prompted diversification along with supply chain reforms to reduce price swings caused by mining, processing, and geopolitical factors. In sum, rare-earth elements continue to be vital to modern technology and 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
