摘　　要：简述了从碲铜渣中综合回收Te、Cu等有价金属的工艺试验。采用“氧化酸浸脱铜→碱浸提碲→酸中和沉碲→络合净化提纯”的工艺对铜碲渣处理得到高纯TeO_(2);含铜溶液置换回收海绵铜;残留渣中的Ag、Se可返回银硒系统回收。The technological test of comprehensive recovery of valuable metals such as Te and Cu from copper tellurium slag was described.High purity TeO_(2) was obtained by the process of"oxidation acid leaching copper removal→alkali leaching tellurium→acid neutralization tellurium precipitation→complexation purification".Copper containing solution replacement recovery sponge copper;Ag and Se in residue can be returned to silver selenium system for recovery.
