【摘要】：安徽某硫化铜锌矿石中的主要有用元素为锌、铜,金、银、硫具有综合回收价值。为了确定该矿石的选矿工艺,采用铜优先浮选—铜粗精矿再磨再选—选铜尾矿依次选锌硫的工艺流程进行了矿石选矿试验。结果表明,矿石在磨矿细度为-0.074 mm占80%情况下进行1次铜粗选,粗精矿再磨至-0.043 mm占93.6%情况下进行2次精选,铜粗选尾矿2次扫选选铜、1粗2精2扫选锌、1粗1精1扫选硫,可获得铜品位为24.80%、铜回收率为80.81%,金、银含量分别22.00 g/t、169.20 g/t,金、银回收率分别为70.97%、63.65%的铜精矿,锌品位为45.48%、锌回收率为87.16%的锌精矿,硫品位为42.80%、硫回收率为59.19%的硫精矿。
[Abstract]:The main useful elements are zinc, copper, gold, silver and sulfur in a copper zinc sulfide ore in Anhui Province. In order to determine the processing process of the ore, the ore dressing experiment was carried out by using the process of copper preferential flotation, copper coarse concentrate regrinding and re-dressing and copper tailings separation. The results show that when the grinding fineness is-0.074 mm, the ore is roughed once, the coarse concentrate is milled to-0.043 mm for 93.6%, and the coarse tailings are cleaned for 2 times. The copper grade is 24.80, the copper recovery is 80.81, the content of gold and silver is 22.00 g / t / t 169.20 g / t, the recovery of gold and silver is 70.97 g / t, respectively, the copper grade is 24.80%, the copper recovery rate is 80.81%, the content of gold and silver is 22.00 g / t ~ (-1) / t ~ (169.20 g / t), respectively. 63.65% of copper concentrate, zinc grade 45.48, zinc recovery 87.16% zinc concentrate, sulfur grade 42.80, sulfur recovery 59.19% sulfur concentrate.
