| Rare earth elements(REEs) play a key role in many industrial fields, which used in additive manufacturing materials and dielectric materials and other high-tech fields, It has expected application prospect. The REEs separation and purification are the key process and link of the REEs resources and the rare earth high-performance and functional materials, so the efficient purification of REEs is particularly important. We analyzed the the advantages and disadvantages and applicability of all these methods, they are classical methods such as chemical precipitation, ion exchange and adsorption, extraction chromatography and solvent extraction, liquid membrane separation and newl methods such as chemical vapor transport, oxidation-reduction method, extraction precipitation, microbial method, non-equilibrium solvent extraction method. This paper focuses on the latest research of these technologies and methods in terms of energy saving. It can provide reference for the green and efficient development and utilization of rare earth resources. The key development directions in the field of rare earth separation and purification were prospected. |
