摘　　要：武平银铜矿矿物间嵌布特征复杂,原有工艺流程选矿指标不是很理想,针对原流程存在的问题,提出铜银混合浮选—混合粗精矿再磨—铜银分离工艺流程,在铜银分离过程中提出通过载体抑制银矿物,即通过使用氧化钙+SD-1组合药剂对银的载体矿物黄铁矿等进行抑制,从而实现铜银的有效分离。通过系统试验研究,最终获得了铜品位为20.29%、铜回收率为56.45%、银品位为1670.50 g/t、银回收率为15.36%的合格铜精矿,以及铜品位为1.19%、铜回收率为36.03%、银品位为742.85 g/t、银回收率为74.32%的合格银精矿。银精矿中铜品位小于2%,有效防止了硫化铜矿在银矿物浸出过程中的不利影响。The embedded characteristic of silver and copper minerals in the ore of Wuping silver-copper mine was complex, and. satisfying index was not obtained by the original process flowsheet, so the process flowsheet of bulk flotation of copper and silver, regrinding of rough-concentrate and separation of silver and copper was proposed in this paper based on the problems existing in the original flowsheet, and for the purpose of inhibitin.g silver minerMs, the inhabitation of carrier was adopted thai meant by adopting the confined reagents of lime and SD-1 to dep.ress the the pyrite and other carrier minerals and it could realize the efficient separation of copper and silver minerals. Through systemic test research, the copper concentrate grading 20.29% Cu was obtained with recovery of 56.45% wh_i_le 1 670.50 .g/t Ag in the copperconcentrate with recovery of 15.36%,- the silver concentrate grading 742.85 g/t Ag with recovery of 74.312%while the content of Cu is 1.19% with recovery of 1.19%. Due to the low grade of copper grade in the silver concentrate （less than 2%）, it could effectively prevent the disadvant＇age influence of copper sulphide on the leaching of silver minerals.
