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。
銅礦石中常伴生金、銀等貴金屬，但浮選所得銅精礦中貴金屬的品位有時低于相關標準而難以計價。針對安徽月山銅礦礦石，在不改變現場浮選設備的情況下，通過浮選藥劑的調整、工藝流程的改進等措施來探討提高銅精礦含銀量的途徑。通過藥劑和工藝調整，銅精礦品位達到32%左右，銅迴收率維持在96.6%以上，同時銅精礦含銀量能夠達到23 g/t以上。

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%.
