Spread the love

Rare earth elements (REEs) are a collection of 17 chemically related metallic elements that are required for the operation of a wide range of modern technologies, infrastructural systems, and renewable energy solutions. The 15 lanthanides—lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium—as well as scandium and yttrium, which have similar chemical properties and frequently occur together in mineral deposits, are included in the definition of rare earth elements.

Despite their name, REEs are not uncommon in the Earth’s crust. They are rather plentiful, but are classified as “rare” because they are rarely discovered in economically useful concentrations. The chemical closeness of these elements makes extraction, refining, and separation extremely difficult, necessitating numerous steps of sophisticated processing.
