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% .
