摘　　要：湿法炼锌产出的高浸渣含锗达150～300g/t,采用两段逆流硫化锌精矿还原浸出,锗的浸出率可达65%以上。并提出了还原浸出的工艺流程和优化浸出条件。The leached slag containing germanium up to 150～300g/t coming from zinc hydrometallurgy process is leached by two step countercurrent reduction leaching process with ZnS concentrate. The germanium leaching rate reaches over 65% in the whole process. The flows of reduction leaching and optical leaching condition are also proposed.
