在过去的十年中，中国稀土工业取得了长足的进步，成为世界上最重要的稀土生产国之一。本文简要综述了近年来在基础研究和工业应用方面的进展：（1）逆流萃取理论的发展与应用;（2）溶剂萃取分离重稀土新工艺及其工业应用（Tm、Vb、Lu）、钇（Y）和钪（Sc），（3）逆流萃取的在线分析和自动控制，（4）四川氟碳铈矿REfTh分离和Eu/RE电化学分离的生态友好工艺流程;（5）我国典型稀土矿物的优化工艺流程。
During the last decade, China rare earth (RE) industry has made significant progress and become one of the most important producers in the world. In this paper, the recent developments in both fundamental research and industrial application are briefly reviewed: (1) the development and application of Theory of Countercurrent Extraction, (2) the novel solvent extraction process and its application in industry for separating heavy rare earth elements (Tm, Vb, Lu), yttrium (Y), and scandium (Sc), (3) the on-line analysis and automatic control of countercurrent extraction, (4) the eco-friendly process for REfTh separation of bastnasite in Sichuan Province and electrochemical process for Eu/RE separation, and (5) the optimized flowcharts for typical rare earth minerals in China.
