摘　　要：对云南某铜矿中伴生金银的性质及其赋存状态进行了详细的研究,并根据研究结论,对现有生产工艺进行了中矿再磨-分级-返回粗选再选的技术改造,在中矿细磨至-0.048mm 63%时,铜精矿中金和银的回收率分别提高了15.2%和15.8%,创造了较高的经济价值,也充分发挥了工艺矿物对选矿的指导作用。The characteristics and occurrence state of associated gold and silver in a Yunnan copper mine were studied in this paper.On the basis of this research results,the technical transformation of middling regrinding-classification—returning roughing for reconcentration was carried on.When the grinding fineness of the middling was-0.048mm63％,the recovery of gold and silver in copper concentrate was increased 15.2％ and 15.8％ respectively,which created a relatively high economic value and played a guiding role of beneficiation.
