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 essential to magnets, catalysts, as well as 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 few nations for mining and processing, driving ongoing diversification efforts and price volatility due to mining, processing, and geopolitical factors. American Molycorp started output at Mountain Pass and targets full capacity in 2014, with a facility at Mountain for processing. Rare earths are found in catalysts and magnets across modern technology, driving clean-energy apps and advanced manufacturing. These worldwide significance has prompted diversification and supply chain reforms to mitigate price swings from mining, processing, and geopolitical factors. Overall, rare-earth elements remain 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]).
