摘　　要：以含锗、铟的锌精炼脱锌氧化硬锌渣为原料,采用氧压酸浸工艺选择性回收其中的锗和铟,并对锗、铟、铜、锡、锑等元素的溶出行为进行了研究。结果表明,锗、铟及锌溶出率分别达到95%、91%及98%以上,大部分铅、硅、锡、锑等则留于残渣中。Germanium and indium are selective recovered from dezincification oxidized hard zinc slag with oxygen pressure leaching process. The dissolving performances of Ge, In, Cu, Sn, Sb were investigated. The results show that the dissolution rates of Ge, In and Zn from the hard zinc slag are up to 95%, 91% and 98% respectively, and most of Pb, Si, Sn and Sb stay in the trail slag.
