摘要
本文扼要叙述了萃取技术在分离科学中的广泛应用，稀土萃取分离工艺（流程）的进展。特别对HEH（EHP）[即P_507萃取剂]的氨化萃取工艺技术、分馏萃取“三出口”分离工艺技术、协同萃取分离方法等作了简要述评．
In this paper,applications of extraction technique has been briefly stated.In separation science,the advances of extraction separation process of rare-earth elements,especialy,ammonia extraction technology of HEH (EHP) [ieP_507extractant].So-called Separation process of“three outputs”,or fractional extraction and the method of separation,or synergistic extraction,was reviewed in detail.
