摘要
在磨矿细度-0.074mm占94%,浮选矿浆温度50℃时,自然pH条件下,硫化钠为调整剂,丁基黄药+丁胺黑药为捕收剂,PZ为起泡剂,通过一粗四精二扫的闭路工艺流程,得到含银3117g/t,回收率70.61%的合格精矿指标,实现了在高温下对中浸渣中有价金属银的回收利用。
When in conditions of grinding fineness -0.074 mm contains 94%,pulp temperature is 50℃,natural pH, sodium sulfide as the adjustment agent, butyl xanthate and D amine black medicine as collector, PZ as foaming agent, through the closed-circuit process of one rough flotation ,two scavengers and four concentratings, qualified concentrate index is gotten： silver 3117 g/t, a recovery of 70.61%, which realizes the recovery of valuable metal silver from neutral zinc leaching slag.
