摘要
为了综合回收某河道堆存尾砂中的铅、锌、硫、砷等有用组分,采用混合浮选-混合精矿分离浮选工艺,最终得到铅锌精矿铅、锌品位分别为2.37%和6.67%,回收率分别为24.73%和57.76%,硫砷精矿硫、砷品位分别为21.56%和7.23%,回收率分别为38.78%和37.39%。
To comprehensively recover valuable elements, including Pb, Zn, S and As, from tailings heaped along a streamway, a flowsheet consisting of a bulk flotation and a flotation separation of bulk concentrate was applied, resulting in a lead-zinc concentrate grading 2.37% Pb and 6.67% Zn with a lead recovery of 24.73% and a zinc recovery of 57.76%, a sulfur-arsenic concentrate grading 21.56% S and 7.23% As with sulfur recovery of 38.78% and arsenic recovery of 37.39%.
