摘　　要：采用废氧加压酸浸新工艺处理铅精矿,将锌、锗、铟等有价金属浸出进入溶液,同时将硫化铅转化硫酸铅进入渣相;该工艺实现了锌、锗、铟与铅的高效分离,锌浸出率可达90%以上、铅绝大部分进入渣相,其流程简单、对环境污染小。The new process that the waste oxygen pressure acid leaching is adopted for treatment of lead concentrate,zinc,germanium,indium and the other valuable metals,which entered into the leaching solution,and at the same time,the lead sulfide is converted to lead sulfate and entered into slag phase;it is realized the efficient separation of zinc,germanium,indium and lead,the recovery rate of zinc can reach to more than 90%,most of lead entered into the slag phase,the flow is simple,which has little pollution to the environment.
