Scarce earth ores are a group of 17 including scandium, yttrium, and the lanthanides ranging from lanthanum to lutetium, found together in many ore sources and critical for magnets, catalysts, and clean-energy tech. Cerium the most plentiful REE in the crust, while promethium is not naturally occurring and has radioactive isotopes. Global supply chains have long depended on a few countries for mining and processing, prompting continuous diversification efforts and price volatility due to mining, processing, and geopolitical factors. U.S.-based Molycorp started output at Mountain Pass and aims for full capacity in 2014, with a separation plant at Mountain to processing. Rare earths are found in catalysts and magnets in modern tech, supporting clean-energy applications and advanced manufacturing. These worldwide importance has led to diversification along with supply chain reforms to mitigate price swings caused by mining, processing, and geopolitical factors. In sum, rare-earth elements remain crucial for modern technology in green energy development.
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
