摘要: 滇西某含锑铅锌硫化矿石铅和锌含量分别为3.91%和1.87%,伴生有价元素为锑、银。为确定该矿石的合适选矿工艺,进行了选矿试验。结果表明,矿石在磨矿细度为-0.074 mm占80%的情况下,采用1粗2扫4精选铅、1粗1扫3精选锌、中矿顺序返回流程处理,获得了铅品位为61.25%、铅回收率为90.40%、含锑6.40%、锑回收率为72.41%、含银39.32 g/t、银回收率为75.62%的铅精矿,以及锌品位为46.57%、锌回收率为81.06%的锌精矿。

Abstract: Contents of lead and zinc in a lead-zinc sulfide ore containing antimony in Western Yunnan are 3.91% and 1.87% respectively,associated valuable elements are antimony and silver.To determine the suitable mineral process,beneficiation experiment was carried out.Results show that lead concentrate with lead grade and recovery rate 61.25% and 90.40% respectively,and containing antimony 6.40% and 39.32% silver,antimony recovery rate is 72.41%,and silver recovery rate is 75.62%,zinc concentrate with zinc grade and recovery rate are 46.57% and 81.06% respectively,was obtained via one roughing-four cleaning-two scavenging lead flotation,one roughing-three cleaning-one scavenging zinc flotation process.
