摘　　要：为提高云南某铜铅锌多金属矿的选矿指标,降低选矿药剂成本,提升经济效益,在矿石性质研究的基础上,进行了铜铅混合浮选工艺试验研究。试验结果表明:在捕收剂丁基黄药+Z-200用量为(50+30)g/t,锌抑制剂硫酸锌+亚硫酸钠用量为(600+300)g/t,起泡剂BK204用量为30 g/t,一段磨矿细度为-0.074 mm80%,粗精矿再磨细度为-0.032 mm90%的条件下,经1粗2扫、1粗精再磨2精的铜铅混合浮选流程,可获得铜品位12.06%、铅品位18.85%、锌品位6.14%、铜回收率87.98%、铅回收率85.33%、锌回收率4.22%的铜铅混合精矿。In order to improve the beneficiation index of a copper-lead-zinc polymetallic ore in Yun⁃nan,reduce the cost of beneficiation reagents and improve economic benefits,based on the study of ore properties,an experimental study on copper-lead mixed flotation process was carried out.The results show that under the conditions of collector butyl xanthate+Z-200 dosage of(50+30)g/t,zinc inhibitor zinc sul⁃fate+sodium sulfite dosage of(600+300)g/t,foaming agent BK204 dosage of 30 g/t,primary grinding fineness of-0.074 mm 80%,and coarse concentrate regrinding fineness of-0.032 mm 90%,the copper�lead mixed flotation process of one roughing-two scavenging-one roughing concentrate regrinding-two cleaning is carried out.The copper-lead mixed concentrate with copper grade of 12.06%,lead grade of 18.85%,zinc grade of 6.14%,copper recovery of 87.98%,lead recovery of 85.33%and zinc recovery of 4.22%can be obtained.
