摘　　要：以内蒙古某铜银多金属硫化矿为研究对象,进行工艺矿物学分析和浮选试验研究。矿石性质研究结果表明,原矿中除了少量黄铜矿、闪锌矿与方铅矿以外,铜银主要以银黝铜矿形式存在。浮选试验研究表明,首先采用铜银混合浮选流程,实现铜银矿物与闪锌矿的分离,其次对混合浮选精矿进行再磨浮选,实现铜银与方铅矿的分离,最终确定了铜银混合浮选—混浮精矿再磨—铜银浮选精选的工艺流程。闭路试验获得了铜品位为18.98%、回收率为80.98%,银品位为10521.88 g/t、回收率为89.81%的铜银精矿,浮选尾矿给入后续的铅锌分离作业,实现了铜银矿产资源的高效综合利用。Taking a copper-silver polymetallic sulfide ore in Inner Mongolia as the research object,the process mineralogy analysis and flotation tests were carried out.The research results of ore properties show that except for a small amount of chalcopyrite,sphalerite and galena in the raw ore,copper and silver mainly exist in the form of silver tetrahedrite.The flotation tests show that,firstly,the copper-silver mixed flotation process is used to realize the separation of copper-silver minerals and sphalerite.Secondly,the mixed flotation concentrate is reground and floated to realize the separation of copper-silver and galena.Finally,the process flow of copper-silver mixed flotation-regrinding of mixed flotation concentrate-copper-silver flotation concentration is determined.The copper-silver concentrate with copper grade of 18.98%,copper recovery rate of 80.98%,silver grade of 10521.88 g/t and silver recovery rate of 89.81%is obtained by closed-circuit test.By feeding the flotation tailings into the subsequent lead-zinc separation operation,the efficient comprehensive utilization of copper-silver mineral resources has been realized.
