摘　　要：四川某铜矿以铜为主要回收对象,其铜矿物主要是辉铜矿和孔雀石,另外含有少量斑铜矿和和黄铜矿,主要伴生矿物为银,具有综合回收价值。矿石氧化率为25.00%,属于硫化氧化混合矿。根据矿石性质,进行了伴生银的综合回收试验研究,通过适当降低铜精矿品位,能将Cu金属的回收率提高3.32%,Ag金属的回收率提高13.47%,获得了较好的经济效益。The copper in a copper ore in Sichuan was acted as the main research object. Chalcocite and malachite are the main minerals and a small amount of bomite and chalcopyrite were also included. Silver was the main associated mineral,which has the value of comprehensive recovery. The ore oxidation rate is 25. 00%,which belongs to sulfide oxide mixed ore. According to the ore properties,study on comprehensive recovery of the associated silver was carried on. Through the reduction of the grade of copper concentrate,the recovery of copper was increased3. 32% and the recovery of Ag was increased 13. 47%. The economic benefit is relatively good.
