【摘要】：广西某复杂铜铅锌多金属硫化矿石铜、铅、锌、硫、银含量分别为0.64%、0.46%、1.66%、10.08%、33.99g/t,主要金属矿物为黄铜矿、方铅矿、闪锌矿、黄铁矿,矿石中金属矿物之间共生关系密切、嵌布粒度不均匀。为确定该矿石的高效开发利用工艺,进行了选矿试验。结果表明:在磨矿细度为-74μm占75%情况下,采用1粗2精2扫铜铅混浮—1粗1精1扫铜铅分离—1粗1精2扫浮锌—1粗1精1扫浮硫流程处理矿石,可获得Cu品位为23.76%、铜回收率为83.93%、Ag品位为556.76 g/t、Ag回收率为36.81%的铜精矿,Pb品位为48.23%、Pb回收率为64.81%、Ag品位为1 651.76 g/t、Ag回收率为30.49%的铅精矿,Zn品位为45.81%、Zn锌回收率为88.49%、Ag品位为71.34 g/t、Ag回收率为6.69%的锌精矿,以及S品位为44.75%、S回收率为81.39%、Ag品位为37.71 g/t、Ag回收率为20.34%的硫精矿,实现了铜、铅、锌、银、硫的高效综合回收。
[Abstract]:The contents of copper, lead, zinc, sulfur and silver in a complex copper-lead-zinc polymetallic sulphide ore in Guangxi are 0.64 and 0.46 and 1.66 respectively. The main metal minerals are chalcopyrite, galena, sphalerite, pyrite and metal minerals in ore. In order to determine the high efficiency development and utilization process of the ore, the ore dressing test was carried out. The results showed that when the grinding fineness was -74 渭 m to 75%, The flotation process of 1 thick 2 fine 2 sweep copper lead mixed floatation 1 thick 1 fine copper lead separation 1 1 coarse 1 fine 2 refined zinc 1 1 fine 1 fine sulfur was used to treat the ore. The copper grade is 23.76, the copper recovery is 83.933%, the copper recovery is 556.76 g / t Ag 36.81%, the copper concentrate is 48.23 and the Pb recovery is 64.81%, the recovery rate is 1 651.76 g / g TU Ag 30.49%, the Zn grade of lead concentrate is 45.81% Zn-Zn recovery is 88.49 g / t Ag, the Ag grade is 71.34 g / t Ag, the recovery rate of lead concentrate is 30.49%%, the recovery rate of Zn and Zn is 88.49 g / t Ag = 71.34 g / t ~ (-1) Ag. Zinc concentrate with yield of 6.69%, The sulfur concentrate with S grade of 44.75 and recovery of 81.39 and Ag of 37.71 g / t ~ (-1) Ag is 20.34%. The high efficiency comprehensive recovery of copper, lead, zinc, silver and sulfur is realized.
