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 ...
Thus an indication of these minerals being short in supply and allocated their title as 'rare' earth minerals. [4] Many rare-earth minerals include rare-earth elements which thus hold the same significant purpose of rare-earth minerals. [5] Earth's rare minerals have a wide range of purposes, including defense technologies and day-to-day uses. [6]
On November 30, 2023, the Ministry of National Security of China defined critical minerals [e] as "those irreplaceable metal elements and mineral deposits used in advanced industries, such as new materials, new energy, next-generation information technology, artificial intelligence, biotechnology, edge-cutting equipment manufacturing, national ...

See: Rare earth industry in China.) Although current evidence suggests rare-earth elements are less abundant on the Moon than on Earth, [60] NASA views the mining of rare-earth minerals as a viable lunar resource [61] because they exhibit a wide range of industrially important optical, electrical, magnetic and catalytic properties.

Kvanefjeld (or Kuannersuit), in Greenland, is the site of a mineral deposit, which is claimed to be the world's second-largest deposit of rare-earth oxides, and the sixth-largest deposit of uranium. [ 1 ] [ 2 ] There are also substantial sodium fluoride deposits, and Kvanefjeld is thought to be one of the largest multi-element deposits of its ...

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.
