Research Progress on Extraction Process of Rare Earth Element Cerium
Cerium(Ce)is one of the rare earth element series.With the development of high technology,the application demand of cerium element in environmental protection,industrial production,optics and materials fields is increasing.At present,commercial scale mining of cerium containing minerals has been achieved,including fluorocarbon cerium ore and monazite.This article mainly summarizes the research progress on metallurgical processes for selecting cerium containing ores using methods such as reselection,magnetic separation,electrostatic separation,and flotation,and then extracting cerium elements from cerium containing concentrates using adsorption,chemical precipitation,and solvent extraction methods.This provides research ideas for the development of efficient and environmentally friendly extraction technologies and the preparation of high-quality cerium element products to meet market demand.
