| 摘 要： | 针对某复杂难选铅锌矿贫铅高锌、铅矿物氧化率高,且与脉石矿物包裹严重,锌矿物共生关系复杂的特点,采用铅锌依次优先浮选的原则流程,以新型组合剂T9作为铅、锌矿物浮选的调整剂,高效组合剂XK-28作为铅矿物的捕收剂,较好的实现了该铅锌矿物的高效分选,小型闭路试验获得铅精矿含铅49.40%,铅回收率51.71%;锌精矿含锌80.70%,锌回收率86.32%的分选指标。

| Abstract: | Some complex refractory Lead-Zinc ore features low lead and high zinc,high oxidation rate of lead minerals,mallic minerals and gangue minerals formation inclusions,complex intergrowth of zinc mineral.Lead and zinc selective flotation was been used with agent T9 as floatation regulators of lead or zinc ore,and agent XK-28 as lead mineral collectors,better separation of lead and zinc mineral was achieved.Small closed-circuit test showed indicators of lead concentrate containing lead 49.40%,lead recovery rate of 51.71%,zinc concentrate containing zinc 80.70%,zinc recovery rate 86.32%. |
