针对云南某铅锌矿铅品位低、锌品位高、矿物组成复杂的特点,通过合理确定工艺及流程,在磨矿细度-0.074mm占78%,使用水玻璃抑制硅酸盐脉石性矿物,以硫酸锌+亚硫酸钠做锌的抑制剂,丁胺黑药和乙硫氮组合作为铅的捕收剂,以丁基黄药作锌的捕收剂的条件下,采用优先浮选流程回收铅锌矿物,最终获得了铅精矿品位58.65%、回收率85.20%,锌精矿品位56.82%、回收率87.50%的良好指标,实现了铅锌矿物的有效分离。
According to the characteristics of low lead grade, high zinc grade and complex mineral composition in a lead-zinc mine in Yunnan Province, the fineness of mineralization of -0.074mm accounted for 78% by reasonably determining the process and flow, and the use of sodium silicate to inhibit silicate mineral , Zinc sulfate + sodium sulfite as zinc inhibitor, butylamine black drug and diethyl sulfanil as lead collector, butyl yellow drug as zinc collector, using preferential flotation process to recover lead Zinc mineral finally got the good grade of 58.65%, the recovery rate of 85.20%, the grade of zinc concentrate of 56.82% and the recovery rate of 87.50%, and achieved the effective separation of lead and zinc minerals.
