从铅锌生产尾料中综合回收锗镓铟

Comprehensive recovery of germanium,gallium indium tailings f rom lead and zinc production

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。

Abstract:

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， .
