采矿损失率定额的制定方法在很大程度上决定于开采方法和选矿必要性。从表1得出,苏联黑色冶金部生产的大部分(81％)矿石是露天法开采的贫矿,需要选矿处理。为保护矿物资源可以增加劳力、材料和电能等资源的消耗。例如,为极大地降低富矿损失,允许降低含铁量相增加硅石含量而 The methodologies for setting quotas for mining loss rates are largely dictated by the mining methods and the need for beneficiation. As can be seen from Table 1, the majority (81%) of the ore produced by the Soviet Union’s Black Metallurgy Division is lean ore mined in the open pit and requires beneficiation. To protect mineral resources can increase the labor, materials and energy consumption and other resources. For example, to significantly reduce the loss of rich ore, allowing a reduction of the iron content to increase the silica content
