降低采矿过程中的贫化率和损失率,是矿山企业增加生产、降低成本、充分利用矿产资源和延长矿山寿命的重要措施,也是衡量一个矿山开采经济效果好坏的重要指标之一.因为,矿石贫化后,必然降低出矿品位、增加无效运输量和后续工序的设备负荷;矿石损失过大,必然引起采矿成本增高,矿山服务年限缩短,所有这
Reducing the rate of depletion and loss in the mining process is an important measure for mining enterprises to increase production, reduce costs, make full use of mineral resources and prolong the life of a mine, as well as one of the important indicators for measuring the economic performance of a mining operation because, After the ore is depleted, it is inevitable to reduce the ore grade, increase the ineffective transportation capacity and equipment load of subsequent processes. Ore loss is too large, which inevitably causes the increase of mining cost and shorten the service life of mine, all of which
