A Look at Rare Earth Metals and Their Applications

Great quantities of rare earth ores were found in California in 1949, and more are being sought throughout North America, but current mining is not significant enough to strategically control any portion of the global rare earths market (the Mountain Pass mine in California still has to ship its minerals to China to be processed).

Mining

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Rare earth element

A rare earth element (REE) or rare earth metal (REM), as defined by the International Union of Pure and Applied Chemistry, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare earth elements because they tend to occur in the same ore deposits as the lanthanides and
