摘　　要：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MIBC,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1.98g/t、银品位26.15g/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6000g/t(pH=11.2)降至3000g/t(pH=9.8),最终可获得铜品位23.02%、回收率92.65%,金品位20.32g/t、回收率50.88%,银品位267.35g/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 .
