摘　　要：为了提高花牛山铅锌硫化矿石中伴生银的回收率,进行了原矿工艺矿物学和银赋存状态研究,在此基础上,采用混合用药、适当降低铅精矿主品位、粗精矿再磨等多种技术措施,使伴生银的回收率有了较大幅度的提高,同时,铅、锌主金属的选矿指标也得到了改善。The paper studied the characteristics of mineralogy of ore and the occurrence condition of silver in order to improve the accompanying silver rocovery of rate in Huaniushan lead-zinc sulfide mine. The results showed, through adopted to adding the combined reagent, cutting down properly the lead grade of flotation in major concentration, regrinding the rougher concentrate, and such sorts separate technology, that the reeovery of accompanying silver was improved apparenlty, and created a better separation index of lead-zinc major metals.
