| 中文摘要: |
| 某高砷富银铋硫矿为硫化矿混合精矿，表面受到浮选药剂污染，各种矿物之间的可浮性相近，给分离带来不利影响。采用“混合精矿加温脱药-脱药精矿铋银优先浮选-铋银尾矿砷硫活化浮选”工艺流程进行处理，采用高效银铋捕收剂SAC，全流程实验获得的银铋精矿含银4386 g/t、铋13.06%、砷0.61%，回收率为银88.52%，铋85.51%；砷硫精矿含硫36.37%、砷9.69%，回收率为硫93.71%，砷97.57%。实现了混合精矿中铋银砷硫的综合回收。 |

| A high As rich Ag-Bi-S polymetallic ore is a mixed sulphide ore concentrate, the surface of which is contaminated with flotation reagents, and the floatability of various minerals is similar, which adversely affects the separation. Adopting the process of "mixed concentrate heating and removing drug-preferential flotation of bismuth and silver demedicated concentrate-arsenic and sulfur activated flotation of bismuth and silver tailings |
