摘　　要：试验采用浮选柱一次粗选、一次精选、一次扫选的全流程闭路正浮选工艺,对金矿氰化浸渣进行柱浮选研究,结果表明给矿金品位0.91 g/t时,精矿金品位31.75 g/t,金回收率27.93%。由于后期给矿性质的变化,着重对浮选柱的设备性能进行了检验,对比了包括超声处理等各参数对浮选效果的影响。Study has be carried system, which included one-stage of ro out for recovering the gold in cyanide residue by column flotation ughing , one-stage of cleaning and one-stage of scavenge column in a closed-circuit separately, as a result, the concentrate grade of Au is 31.75 g/t,and the recovery of Au is 27.93% under the condition with crude grade of 0.91 g/t. Aiming to the changing feeding ore property at later stage, the column flotation equipment performance has been tested and the influence of different parameters such as ultrasound approach to the flotation process is compared as well.
