【摘要】：四川会东某高泥铅锌矿石主要有价组分铅、锌、银含量分别为1.01%、6.30%、34.89 g/t,铅矿物以方铅矿为主,锌矿物以闪锌矿为主。由于现场浮铅时抑锌效果不理想,即使浮选工艺流程冗长,但铅、锌精矿指标仍不理想。试验引进新型、高效抑制剂XKY-02配合硫酸锌抑锌浮铅,再活化选锌,在磨矿细度为-200目占80%的情况下,采用1粗2精1扫浮选选铅、1粗1精1扫浮选选锌、中矿顺序返回流程处理矿石,获得了铅品位为55.77%、银品位为571.72 g/t、含锌6.70%、铅回收率为71.05%、银回收率为21.17%的铅精矿,以及锌品位为56.06%、银品位为244.87 g/t、含铅1.04%、锌回收率为92.59%、银回收率为72.99%的锌精矿。与现场工艺相比,铅、锌选矿工艺段数明显减少,但精矿指标明显改善。
[Abstract]:Sichuan Huidong Lead zinc ore with high mud mainly a valuable component of lead, zinc and silver content were 1.01%, 6.30%, 34.89 g/t, lead mineral galena and sphalerite. Due to zinc mineral lead zinc floating field suppression effect is not ideal, even if the flotation process is lengthy, but the index is still not lead, zinc concentrate ideal. The introduction of a new type of test, with efficient inhibitors of XKY-02 zinc sulfate zinc lead to activation of anti floating, zinc ore accounted for 80%, -200 in grinding fineness under the condition of using 1 2 coarse fine 1 sweep of flotation of lead, 1 1 coarse fine 1 sweep of flotation of zinc, middling return order process to obtain ore the lead grade is 55.77%, the grade of silver was 571.72 g/t, containing 6.70% zinc, lead recovery rate is 71.05%, the recovery rate of silver is 21.17% lead concentrate, zinc and silver grade is 56.06%, 244.87 grade g/t, 1.04% of lead and zinc recovery rate was 92.59% and the recovery rate of silver was 72.99%. Compared with the zinc concentrate. The process of lead and zinc. The number of beneficiation process segments is obviously reduced, but the index of concentrate is obviously improved.
