摘　　要：该矿在预先脱碳过程中,黄铜矿随碳质浮出。可利用黄铜矿与碳质密度差异进行碳铜分离。由于近30%的氧化铜矿以吸附状态赋存在褐铁矿中,造成此部分氧化铜难以回收。经多方案试验确定宜采用重选—浮选联合工艺流程,其最终获得了铜品位13.02%、回收率57.95%的技术指标。During preliminary carbon stripping process,chalcopyrite floats with carbon.Charcopyrite and carbon can be separated due to their different density.Because nearly 30% of the copper oxide is deposited in limonite,it is very difficult to recover this portion of copper oxide.After several tests,the process of gravity-flotation is determined to achieve a copper grade of 13.02% and a recovery rate of 57.95%.
