摘　　要：以内蒙较大型锌矿选矿精矿为研究对象,最终确立焙烧-硫酸浸锌、铜-氰化浸银工艺。Zn、Cu、Ag浸出率分别为95.01%、94.13%、89.10%,并具有试剂耗量低、技术简单、易实施等优势。A new metal extraction and separation process of zinc/silver/copper from complex zinc concentrates has been developed in which zinc is extracted through roast and sulphuric acid leaching while the residue is treated by cyanidation to leach silver. With low reagent consumption, the process is easily carried corresponding to leaching rates of 95.01% Zn, 94.13%Cu and 89.10% Ag, respectively.
