Rare earth minerals and classificationMetalpedia

Rare earth minerals and classification; Rare earth minerals; In the earths crust, instead of existing as free metals, rare earth elements usually occur in the minerals of mixtures of various rare earth elements and nonmetals. More than 200 kinds of minerals have been discovered to contain essential or significant REE currently, and bastnaesite, monazite and xenotime are the three most

HREE = heavy rareearth elements; MREE = middle rareearth elements; Discovery and early history. The first rareearth element discovered was the black mineral quot;ytterbitequot; (renamed to gadolinite in 1800). It was discovered by Lieutenant Carl Axel Arrhenius in 1787 at a quarry in the village of Ytterby, Sweden.
