矿石的损失率和贫化率,是矿床开采的重要技术经济指标,也是衡量一个矿山的技术水平和管理水平的重要指标之一。在实际生产过程中,一些矿山对矿损、贫化并没有给予足够重视,也没有进行准确的计算与系统分析,因此,造成了一定的经济损失。 The loss rate and depletion rate of ores are important technical and economic indicators for the mining of the ore and are also one of the important indicators for measuring the technical level and management level of a mine. In the actual production process, some mines did not pay enough attention to mineral loss and depletion, nor did they make accurate calculations and systematic analyzes. As a result, some mines caused some economic losses.
