| Abstract: Based on the Theory of Countercurrent Extraction, establisehed by Professor Guang-Xian Xu in the 1970′s, the rare earth (RE) industry of China has made significant progress and become the most important RE producer in the world. In this paper, the recent developments in both fundamental research and industrial application work in Peking University are briefly reviewed: (1) the development and application of Theory of Countercurrent Extraction, (2) the solvent extraction process and its application in industry for separating heavy rare earth elements (Tm, Yb, Lu), yttrium (Y), and scandium (Sc), and (3) the on-line analysis and automatic control of countercurrent extraction. | |
