矿石回收率,又称采矿回收率,是地下矿产资源采出数量的百分比。它是评定采矿工作质量高低和地下矿产资源利用程度的一个非常重要的技术指标。它的基本概念和计算方法必须能够确切反映采矿生产的实际情况。 长期以来,国内外在理论工作和实际工作中,把矿石回收率制定为采出矿石量与工业矿石量之比,并按下列公式计算,即 Ore recovery rate, also known as mining recovery rate, is a percentage of the amount of underground mineral resources recovered. It is a very important technical indicator for assessing the quality of mining work and the degree of utilization of underground mineral resources. Its basic concepts and calculation methods must be able to accurately reflect the actual situation of mining production. For a long time, both at home and abroad in the theoretical work and practical work, the ore recovery rate is formulated as the ratio of the amount of ore ore mining and industrial ore, and according to the following formula, that is
