Selective Crystallization and Separation of REEs in RE-Concentrate

Reports the selective crystallization and separation of REEs in RE-concentrate. The mineral evolution and mineral reconstruction behaviors of RE-concentrate are reported, and the study on selective concentration and selective separation of cerium oxyfluoride in RE-concentrate is included in Sects. 5.1 and 5.2, respectively. The study on stepwise crystallization, stepwise concentration, and stepwise separation of REEs (Ce, La, Pr, Nd) in RE-concentrate is included in Sect. 5.3.
