摘　　要：针对某银多金属硫化矿易浮难分离的特点,采用优先浮选铜的工艺流程,用Z-200作捕收剂,石灰石、亚硫酸钠、硫酸锌、羧甲基纤维素钠作抑制剂,获得铜精矿含铜20.01%、铜回收率72.26%,含金52.60g/t、回收率70.73%,含银6455g/t、回收率86.62%的较好指标。The silver-containing multimental sulphide ore is treated by prior floatation technique,because the mineral is easily-floated but hard-separated.Z-200 collector and inhibitors of limestone,sodium sulfite,zinc sulfate and CMC are adopted,copper concentrate containing copper was 20.01%,72.26% recovery rate;aurum was 52.60 g/t,70.73% recovery rate;argentum was 6455 g/t,86.62% recovery rate.
