What are the Rare-Earth Elements? The REE group is composed of 15 elements that range in atomic number from 57 (lanthanum) to 71 (lutetium) on the periodic table of elements, and are officially referred to as the “lanthanoids,” although they are commonly referred to as the “lanthanid” The rare-earth element promethium (atomic .
The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanid The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's

Rare earth elements-bearing minerals, once separated, contain as many as 14 individual rare earth elements (lanthanides and yttrium) that must be further separated and refined The complexity of extracting and refining rare earth elements is illustrated by a metallurgical flow sheet for the Mountain Pass mine in California (fig 2)
The rare earth metals are a family of 17 elements consisting of scandium, yttrium, and the lanthanum-group elements The term "rare earths" is a misnomer, as some of these elements are not particularly rare and all of them are metals, not earths The elements are ,
Why rare-earth mining in the West is a bust — High Country ,
Each successive rare earth element adds one more proton and one more electron It’s significant that there are 15 rare earth elements: Chemistry students may recall that when electrons are added to an atom, they collect in groups or layers, called orbitals, which are like concentric circles of a target around the bull’s-eye of the nucleus
