从铅锌生产尾料中综合回收锗镓铟

摘要

从铅锌生产尾料中综合回收锗镓铟，采用先蒸馏提取锗，镓和铟留在蒸馏残酸母液中，通过使用萃取剂A萃取镓，再用萃取剂P204萃取铟的方式生产，锗的回收率可达90％以上，镓回收率88％以上，铟回收率90％以上。%In this work ,extraction techniques for germanium ,gallium ,and indium from the raw material of germanium containing high percentages of zinc ,arsenic ,gallium ,and indium are presented .After distil-lation of germanium ,indium and gallium are kept in the mother solution .Gallium was then extracted by A ,whereas indium by P204 .The extraction efficiencies of germanium is larger than 90% .The extraction efficiencies of gallium is more than 88% .The extraction efficiencies of indium is more than 90% .
