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。A high-dirt lead-zinc ore in Huidong County,Sichuan Province contain main useful elements including 1.01% Pb,6.30% Zn,and 34.89 g/t Ag with lead existing in galena and zinc in sphalerite respectively.The original process has nota good effect of zinc suppression when lead floats.Even the flotation technology is complicated,the indexes of lead concentrateand zinc concentrate are still worse.XKY-02,a new type of efficient inhibitor,was introduced,mixed with zinc sulfate to inhib-it zinc and float lead.Then,it was used to activate zinc concentration.With the grinding fineness of 80% passing 200 mesh,and by the process of one-roughing,two-cleaning and one-scavenging,and middling back to the flow-sheet,lead concentratewith lead grading 55.77% Ag grade of 571.72 g/t,6.70% Zn and Pb recovery of 71.05% and Ag recovery of 21.17%,andzinc concentrate with zinc grade of 56.06%,Ag grade of 244.87 g/t,Pb 1.04%,Zn recovery of 92.59% and Ag recovery of 72.99% were obtained respectively.Compared with the on-site process,the flow-sheet number is obviously less,but the indexof the concentrates are greatly improved.
