为实现西南某铜金硫多金属矿在低碱环境下的浮选分离，对硫化铜矿捕收剂 PZO的性能进行了研究．结果表明，PZO的起泡性能不仅优于2号油和 M IBC ，而且对硫化铜矿和自然金的选择捕收效果优于丁铵黑药和丁基黄药．在原矿铜品位1．23％、金品位1．98 g/t、银品位26．15 g/t、硫品位12．68％时，采用组合药剂丁基黄药＋PZO作捕收剂，铜硫分离时将石灰用量从丁基黄药＋2号油组合时的6000 g/t（pH＝11．2）降至3000 g/t（pH＝9．8），最终可获得铜品位23．02％、回收率92．65％，金品位20．32 g/t、回收率50．88％，银品位267．35 g/t、回收率56．50％的铜精矿，以及品位41．52％硫精矿的良好指标．

In order to recover copper sulphides in weak alkaline solution , the floatation performance of gold-bearing minerals and the collector PZO have been studied .T he result show s that PZO has better foam ability than 2# oil and MIBC ,and also has better selectivity to copper and gold minerals than both ammo-nium dibutyl dithiophosphate and butyl xanthate .When the raw ore contained 1 .23% Cu ,1 .98g/t Au , 26 .15g/t Ag and 12 .68% S ,the flow sheet of “Cu-S bulk flotation-Cu-S separation”was adopted by using combined collector of butyl xanthate and PZO ,the lime dosage could reduce from 6000g/t (pH=11 .2) to 3000g/t (pH=9 .8) ,which creates conditions for improving gold floatation performance .a copper concen-trate assaying 23 .02% Cu with a recovery of 92 .65% ,assaying 20 .32g/t Au with a recovery of 50 .88% , assaying 267 .35g/t with a recovery of 56 .50% could be obtained , and a sulfur concentrate assaying 41 .52% could also be obtained during the Cu-S separation process .
