摘　　要：以小秦岭某多金属金矿为研究对象 ,最终确定采用焙烧—硫酸浸铜—盐浸铅—氰化提金、银工艺分步分离回收铜、铅、金、银。试验结果表明 ,其铜、铅、金浸出率分别达到了 97.0 5 %、89.90 %、96.91%。By means of the Xiaoqinling polymetallic sulfide ores as the object of study,an experimental research on comprehensive utilization of the mineral resources was performed.On the basis of analysis of experimental results,a fractional separation technology comprising sulfuric acid leaching of copper-salt solution leaching of lead-cyanide leaching of gold and silver was finally determined.Experimental results showed that the leaching rates of 97.05%Cu,89.90%Pb,96.91%Au have been attained with the low-cost and easily-operation technology.This new technology of comprehensive utilization is also suitable for treating other similar mineral resources.
