Rare Earths Statistics and Information - USGS

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 lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's

Rare Earth Properties - ThoughtCo

Jun 22, 2018  The rare earths share many common properties. This makes them difficult to separate or even distinguish from each other. There are very small differences in solubility and complex formation between the rare earths. The rare earth metals naturally occur together in minerals (e.g., monazite is a mixed rare earth phosphate).
