| 中文摘要: |
| 某富银铜锌多金属硫化矿，其银品位为125 g/t，铜品位为0.26%，锌品位为1.13%，硫品位为3.04%；90%的银赋存于银黝铜矿、黝铜矿等铜矿物中。采用“优先浮银铜﹣锌硫混浮﹣锌硫分离”工艺流程进行处理，选择高效银捕收剂SAC强化银的回收，全流程实验获得的银(铜)精矿含银10094 g/t，含铜16.67%，银回收率88.78%，铜回收率80.23%，锌精矿含锌45.46%，锌回收率81.81%。实现了矿石中银铜锌的综合回收。 |
| 英文摘要: |
| A sliver-rich copper-zinc polymetallic sulfide ore has a silver grade of 125 g/t, copper grade of 0.26%, zinc grade of 1.13%, sulfur grade of 3.04%. 90% of silver occurs in copper minerals such as silver tetrahedrite and tetrahedrite. Adopting the process of “priority floating silver copper - zinc sulfur mixed floating - zinc sulfur separation” and using high-efficiency silver collector SAC, the silver grade of the silver-copper concentrate obtained by the whole process experiment is 10094 g/t with an 88.78% silver recovery rate, and the grade of copper is 16.67% with an 80.23% silver recovery rate. The zinc grade in the zinc concentrate is 45.46%, and its recovery rate is 81.81%. Comprehensive recovery of silver, copper, and zinc in rich Ag-Cu-Zn polymetallic ore is achieved. |
