迈卡因选矿厂目前正在处理‘B’矿床的矿石,由于它的矿物组分复杂,硫化物细粒浸染及其互为伴生,很难选。不同类型的矿石沿矿层走向的产状不均一和主要元素含量的变化导致工艺流程的部分破坏。在采矿中和选矿前准备,矿石没有混匀,造成处理时的困难。矿石含有大量的贵重金属,在选矿时只有35～40％回收到铜精矿中。由于它在黄铁矿精矿和重晶石精矿以及在固相和液相最终尾矿中的大量丢失,迈卡茵选矿厂商品精矿中贵重金属的总回收率很少超过70％。在不降低主要金属回收率和精矿质量的条件下,提高铜-铅浮选回路中贵重金属的回收率是困难的。改进工艺和减少贵金属在锌-黄
The McCain beneficiation plant is currently processing the ore from the ’B’ deposit, which is difficult to pick because of its complex mineral composition, sulphide fines disruption and their interdependence. Different types of ores along the direction of the formation of non-uniform occurrence of the main elements and lead to changes in the process led to the partial destruction. Preparation in the mining and dressing, the ore is not mixed, resulting in difficulties in handling. Ore contains a lot of precious metals, ore beneficiation only 35 ~ 40% recovered into the copper concentrate. The total recovery of precious metals in commodity concentrates at the McCarrain concentrates seldom exceeds 70% due to its large losses in pyrite concentrates and barite concentrates and in the final tailings of solid and liquid phases. It is difficult to increase the recovery of precious metals in the copper-lead flotation loop without reducing the recovery of major metals and the quality of the concentrate. Improve the process and reduce the precious metal in zinc-yellow
