A process

Naming Rare earths, "rare" is induced by the complexity of separating them from each other to obtain pure elements. This process requires specialized know-how and expertise.

Nowadays, the benchmark technology for purifying rare earths at industrial scale is solvent extraction. Two types of solvent extraction are used so far: hydrochloric acid based and nitric acid based.
