| 中文摘要: |
| 铜矿石中常伴生金、银等贵金属，但浮选所得铜精矿中贵金属的品位有时低于相关标准而难以计价。针对安徽月山铜矿矿石，在不改变现场浮选设备的情况下，通过浮选药剂的调整、工艺流程的改进等措施来探讨提高铜精矿含银量的途径。通过药剂和工艺调整，铜精矿品位达到32%左右，铜回收率维持在96.6%以上，同时铜精矿含银量能够达到23 g/t以上。 |
| 英文摘要: |
| There exist associated precious metals such as gold and silver in copper ores, and the grade of precious metals is less than relevant standard and thus the valuation of these metals is overlooked. The content of silver in copper concentrate from copper mineral of Yueshan Mine was upgraded by adopting some measures, such as adjustment of flotation reagents and technological improvement. Silver content in the concentrate was increased to 23 g/t while copper was elevated to about 32% with a recovery of 96.6%. |
