摘要: 云南某铜铅锌多金属矿石铜、铅、锌含量分别为1.08%、1.51%、2.36%。为开发利用该矿石,对其进行了选矿试验研究。结果表明:原矿磨细至-0.075 mm占72.50%,以硫酸锌+EMT-12为抑制剂、EMS-602为捕收剂经1粗3精1扫优先选铜,选铜尾矿以石灰为调整剂、硫酸锌+EMT-12为抑制剂、EMS-001为捕收剂经1粗3精1扫选铅,选铅尾矿以硫酸铜为活化剂、丁基黄药+乙基黄药为捕收剂经1粗3精1扫选锌、选锌尾矿以EMH104+硫酸铜为活化剂、丁基黄药为捕收剂经1粗1扫选硫,可以得到铜品位为20.33%、回收率为86.29%的铜精矿,铅品位为55.68%、回收率为84.35%的铅精矿,锌品位为46.83%、回收率为86.97%的锌精矿,硫品位为38.96%、回收率为71.92%的硫精矿,达到了对铜、铅、锌、硫综合回收的目的。

Abstract: There is 1.08% copper,1.51% lead,and 2.36% zinc in a polymetallic Cu-Pb-Zn ore in Yunnan.For the development and utilization of the ore,experiment study on the ore was conducted.Results show that at grinding fine of 72.5% passing 0.075 mm,using zinc sulphate+EMT-12 as depressor,EMS-602 as collector via one roughing-three cleaning-one scavenging copper flotation,copper flotation tailing using lime as regulator,zinc sulfate+EMT-12 as depressor,EMS-001 as collector via one roughing-three cleaning-one scavenging lead flotation,lead flotation tailing using copper sulfate as activator,butyl xanthate+ethyl xanthate as collector via one roughing-three cleaning-one scavenging zinc flotation,zinc flotation tailing using EMH104+copper sulfate as activator,butyl xanthate as collector via one roughing-one scavenging sulfur flotation,copper concentrate with copper grade of 20.33% and recovery of 86.29%,lead concentrate with lead grade of 55.68% and recovery of 84.35%,zinc concentrate with zinc grade of 46.83% and recovery of 86.97%,sulfur concentrate with sulfur grade of 38.96% and recovery of 71.92% were obtained.Comprehensive recovery of copper,lead,zinc,sulfur was realized.
