摘　　要：分析了某难选、高砷多金属硫化铜矿石的特点,即有用矿物成分多、品位较低。经过初步浮选试验研究,采用混合浮选再分离的工艺流程,获得品位25.66%、回收率73.39%的铜精矿,为进一步深入试验做好了准备。The characteristics of some high arsenic-bearing poly-metallic sulphide copper ore were analyzed. There were many useful minerals in the experiment ore, but the grades were low and it was difficult to be dressed. The preliminary flotation test results showed that using the bulk flotation-reseparation process could achieve copper concentrate with grade 25.66% and recovery 73.39%. It laid the foundation for further tests.
