摘　　要：本文基于物料平衡，从理论上讨论了稀土溶剂萃取分离（组）三出口工艺中间产品分离指标的设定范围，为工艺设计和其他分离指标的计算提供了理论依据。The tri-exit extraction separation process(TESP) has been widely used in theseparation of rare earths. Generally,there are six separation indexes(purities P_A,P_B,P_C,andrecoveries R_A,R_B,R_C),of which four indexes are unknown.And the constituents of materialsf_A,f_B,and f_c are known. Therefore,there are design schemes. In this paper, based onthe principle of material balance,all these schenes will be discussed in regard to the separa-tion indexes, and the formulas for calculating,them and calcuated indexes are provided.
