摘　　要：采用“常压浸出-氧压浸出”工艺从氧化锌烟尘中高效浸出锌、锗、铟。研究了常压浸出、氧压浸出过程中各主要影响因素对锌、锗、铟浸出率的影响。结果表明,在“常压浸出-氧压浸出”最佳工艺条件下,氧压浸出渣中锌、锗、铟的含量为2.26%、99.4 g/t、64.8 g/t,锌、锗、铟累计浸出率可达到96.15%、91.58%、87.90%。High efficient leaching of zinc, germanium, indium in zinc oxide fume was carried out by using of "atmospheric leaching-oxygen pressure leaching " process. Main influencing factors for leaching rate of zinc, germanium, indium in process of atmospheric leaching and oxygen pressure leaching were studied. Results show, under the optimal process conditions of " atmospheric leaching-oxygen pressure leaching ", the content of zinc, germanium, indium in oxygen pressure leaching residues were 2.26 %, 99.4 g/t,64.8 g/t, the accumulated leaching rate can reach to 96.15 %, 91.58 %, 87.90 %.
