The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
The Mountain Pass Rare Earth Mine and Processing Facility, owned by MP Materials, is an open-pit mine of rare-earth elements on the south flank of the Clark Mountain Range in California, 53 miles (85 km) southwest of Las Vegas, Nevada. In 2020 the mine supplied 15.8% of the world's rare-earth production.
Rare-earth ore, shown with a United States penny for size comparison. A rare-earth mineral contains one or more rare-earth elements as major metal constituents. Rare-earth minerals are usually found in association with alkaline to peralkaline igneous complexes in pegmatites. This would be associated with alkaline magmas or with carbonatite ...
Although the roots of rare earth elements (“rare earths”)—a group of 17 elements on the periodic table, which I sometimes fondly refer to as the “mighty 17”—can be traced back to their ...
It offers a huge potential source of domestic rare earth elements without the need for new mining, said Bridget Scanlon, a study author and research professor at UT’s Jackson School of Geosciences.
An overview of one of the regolith-hosted rare earth element deposits (a type of Rare Earth Element mine) in South China [1]. Regolith-hosted rare earth element deposits (also known as ion-adsorption deposits) are rare-earth element (REE) ores in decomposed rocks that are formed by intense weathering of REE-rich parental rocks (e.g. granite, tuff etc.) in subtropical areas.

Discovered in 1949 in San Bernardino County, California, Mountain Pass mine consists of a bastnäsite ore-body with significant concentrations of rare earth elements. [32] The mine once supplied most of the world's rare earth elements. [33] Mountain Pass is the only operational rare earth mining and processing facility in the United States. [10]
China is reportedly moving toward banning rare earth metal exports to keep high-tech advantages within the country.
