摘    要:郴州某冶炼渣中铅、锌、银、铁、硫含量分别为7.23%、5.02%、143.28 g/t、45.70%、21.11%。为开发利用该二次资源,对有代表性试样进行了选矿试验。结果表明:在磨矿细度为-0.074 mm占72%条件下,以硫酸铜为活化剂、生石灰为抑制剂、异丁基黄药为捕收剂,经1粗1扫2精流程选锌,选锌尾矿再磨至-0.038 mm占84%后经1次摇床重选选铅银,可获得锌品位为40.02%、回收率为80.36%的锌精矿,以及铅、银品位分别为45.56%和 1 000.12 g/t,铅、银回收率分别为62.83%和69.59%的铅银混合精矿。

关 键 词:冶炼渣  浮选  再磨  摇床重选

Abstract:There is 7.23% lead,5.02% zinc,143.28 g/t silver,45.70% iron,and 21.11% sulphur in a smelting slag from Chenzhou.Beneficiation experiments were conducted on the typical sample to develop and utilize the secondary resource. The results indicated that,at the grinding fineness of 72%passing 0.074 mm,with copper sulfate as the activator,quicklime as inhibitors and isobutyl xanthate as collector via one roughing-one scavenging-two cleaning closed circuit process for enrichment of zinc,and at the regrinding fineness of 84%passing 0.038 mm via shaking table for enrichment of lead and silver from zinc tailings,zinc concentrate with 40.02% Zn and recovery of 80.36% are obtained,and lead-silver mixed concentrate with 45.56% Pb and recovery of 62.83%,and with 1 000.12 g/t Ag and recovery of 69.59% are obtained.
Keywords:Smelting slag  Flotation  Regrinding  Gravity separation by tabling
