摘　　要：在提取碲的过程中,常将含碲矿物或原料浸出于溶液再进行分离。从含碲溶液中分离提取碲成为广大冶金学者关注的焦点。本文综述了国内外对含碲溶液分离富集碲的工艺方法,着重介绍了液膜分离法、溶剂萃取法、置换法、SO_2或Na_2SO_3还原法、沉淀分离法、微生物法、吸附法、电解法等。In the extraction of tellurium, the tellurium minerals or raw materials are often leached into solution then separated. Thus, the separation of tellurium from Te-containing solution has become the focus of many metallurgists. In this paper, the technology of separation and enrichment of tellurium from Te-containing solutions at home and abroad was reviewed. Emulsion liquid membrane, solvent extraction, displacement method, reduction method by SO2 or Na2 SO3, sedimentation, microbial method, adsorption processes and electrolysis were highlighted.
