摘　　要：针对某铜矿伴生金银回收率较低的问题,进行了工艺矿物学及选矿试验研究。通过不同试验方案研究结果的比较,通过选铜捕收剂的优化,最终闭路试验指标与现场工艺相比,铜、金、银回收率分别较现场工艺流程高0.36%、4.89%和3.29%,铜、金、银回收率均有所提高。In view of the low recovery of associated gold and silver in a copper mine,the process mineralogy and mineral processing experiments were carried out.Through the comparison of research results of different test schemes and optimization of copper collector,the final closed-circuit test indexes were compared with the field process,and the recovery rates of copper,gold and silver were 0.36%,4.89%and 3.29%higher than the field process,respectively,and the recovery rates of copper,gold and silver were improved.
