摘要: 河北省某铜锌多金属硫化矿石黄铁矿含量高,铜锌矿物嵌布关系密切复杂。矿石含铜1.14%、含锌6.67%、含硫29.12%,属于高硫铜锌矿石。为给该矿石合理开发利用工艺提供依据,进行了选矿试验。结果表明:采用1粗1精1扫选铜,选铜尾矿经1粗1精1扫选锌,选锌尾矿经1粗1扫选硫流程,可获得铜品位为24.13%、含锌9.33%、铜回收率为73.86%的铜精矿,锌品位为50.63%、含铜1.95%、锌回收率为91.01%的锌精矿,硫品位为53.34%、硫回收率为74.46%的硫精矿产品。试验结果可以作为该高硫铜锌矿石综合开发利用的依据。

Abstract: The content of pyrite in copper-zinc polymetallic sulfide ore in Hebei Province is high, and the relationship between copper and zinc minerals is closely and complicated. The content of copper, zinc and sulfur is 1.14%, 6.67% and 29.12%, and belongs to high sulfur copper-zinc ore. To provide basis for rational development and utilization of the ore, beneficiation experiment was conducted. Results show that, via one roughing one cleaning one scavenging copper flotation, one roughing one cleaning one scavenging of zinc flotation on copper tailings,one roughing one scavenging of sulfur flotation on zinc tailings, copper concentrate with copper grade of 24.13%,zinc content of 9.33% and copper recovery of 73.86%, zinc concentrate with zinc grade of 50.63%, copper content of 1.95%,and the zinc recovery of 91.01%, sulfur concentrate with sulfur grade of 53.34% and sulfur recovery of 74.46% was obtained. The experimental results can be used as the basis for the comprehensive development and utilization of the high sulfur copper-zinc ore.
