Rare earth metals may be extracted from bastnasite, monazite. Separating and extracting a single rare earth element from the mixed rare earth compound extracted from the concentrate not only separates these dozens of rare earth elements with extremely similar chemical properties, but also must leave the rare earth element and associated impurities. The methods mainly include chemical methods, ion exchange methods, and solvent extraction methods. Industrially used rare earth metals are used in large quantities, and higher purity rare earth metals are mainly used for determining physical and chemical properties. There are currently four main purification methods used in the laboratory, namely vacuum melting, vacuum distillation or sublimation, electromigration and zone melting.
