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: 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 not a good effect of zinc suppression when lead floats.Even the flotation technology is complicated,the indexes of lead concentrate and zinc concentrate are still worse.XKY-02,a new type of efficient inhibitor,was introduced,mixed with zinc sulfate to inhibit 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 concentrate with 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%,and zinc 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 index of the concentrates are greatly improved.
