Selective Crystallization and Separation of REEs in RE-Bearing Slag

It reports the selective crystallization and separation of REEs in RE-bearing slag. The selective crystallization behaviors of RE in RE-bearing slag, including the isothermal phase diagram of CaO–SiO2–CaF2–Ce2O3 system, the phase equilibria of RE-phase, and the isothermal crystallization and growth kinetics of RE-phase are reported, respectively, in Sect. 4.1. The study on selective separation of RE in RE-bearing slag, including the motion and separation behaviors of cefluosil in molten RE-bearing slag, is included in Sect. 4.2.
