摘　　要：山西某铜矿山长期采用丁基黄药作为铜矿捕收剂,生产现场丁基黄药刺激性气味强烈、选矿废水中黄原酸根离子超标。为解决黄药使用的环保问题,针对该铜矿,采用新型环保型捕收剂CYL-5进行浮选试验研究,经一次粗选三次精选一次扫选的闭路浮选流程,取得铜精矿Cu品位为25.13%、回收率为93.30%的浮选指标。与丁基黄药浮选指标相比,铜精矿Cu品位提高2.06百分点,铜回收率提高0.50百分点,可达到优于丁基黄药浮选的目的。Butyl xanthate has been used as copper collector in a copper mine in Shanxi province for a long time.Butyl xanthate has a strong pungent smell on the production site and the xanthate ion in benefication wastewater exceeds the standard.In order to solve the environmental problems of xanthate,Novel environmental collector CYL-5 was used to carry out for flotation experiment in the copper mine.Through the closed-circuit flotation process of one roughing,three cleanings and one scavengings,the copper concentrate with Cu grade of 25.13%and recovery of 93.30%was obtained.Compared with the flotation index of butyl xanthate,the grade of copper concentrate was increased by 2.06 percentage points and the copper recovery was increased by 0.50 percentage points using the collector CYL-5,which was better than butyl xanthate.
