摘　　要：通过采用伯胺N_(1923)与中性膦TBP组成的协同萃取体系,分离回收钼精矿焙烧烟尘中微量铼的工艺流程,比较了此体系在不同条件下对铼（Ⅶ）、钼（Ⅵ）等离子的萃取效率和分离效果。铼在萃取过程中浓缩了20倍以上,整个回收工艺流程简单、分离效果较好。The separation arid recovery process of micro amounts of rehenium from Hue dust of roasted molybdenite mine by synergistic extraction witli primary amino N1923 and neutral phosphorus esters TBP has been studied in this paper. The extraction efficiencies and separaption effects of He(VII),Mo (VI) ions etc. in different conditions have been investigated. Rehenium is concentrated for more than twenty times in the whole process .The steps of the whole process are fewer and the separation efficiency is better.
