提高矿山经济效益的重要途径之一,就是人们常说的“三率一综”,即在矿山生产经营活动中,努力降低开采过程中贫化率、损失率;努力提高选矿过程中金属实收率;大力开展矿石的综合利用。尤其是矿石的综合利用常常可以使一矿变两矿、经济效益翻番的事半功倍的效果。因此,在矿山生产中必须十分注意矿石的综合利用。实践证明,在自然界单一元素的矿床是少数的,而绝大多数矿床都不同程度的存在多元 One of the important ways to improve the economic efficiency of mines is that people often say that “three rates and one comprehensive”, that is, in the mine production and business activities, efforts to reduce the mining process of dilution rate, loss rate; efforts to improve the metal beneficiation process Rate; vigorously carry out the comprehensive utilization of ores. In particular, the comprehensive utilization of ores can often change one ore mine into two and bring about double the economic benefits with a multiplier effect. Therefore, in the mine production must pay great attention to the comprehensive utilization of ore. Practice has proved that in nature a single element of the deposit is a small number, and most deposits are varying degrees of existence of multiple
