发展综合工艺,以便最充分地利用矿物资源,减少尾矿,降低对自然界的不利影响,是强化利用矿物原料资源的重要因素。但是,在开采有色金属矿床时废石率非常高,往往占所采出矿岩总量的95～98%。从长远看,废石总量的增长速度还要增加。很显然,假若考虑到采矿工业中出现的主要趋势——大约每隔10年矿石的采出量就要翻一番,所采原料中的有用组分的含量降低,露天开采深
The development of integrated processes to maximize the use of mineral resources, reduce tailings and reduce the adverse effects on nature is an important factor in enhancing the utilization of mineral resources. However, the rate of waste rock in the exploitation of non-ferrous metal deposits is very high, often accounting for 95-98% of the total amount of ore rock produced. In the long run, the total amount of waste rock will increase even faster. Obviously, given the major trends in the mining industry that roughly doubled the amount of ore that is produced every 10 years, the content of useful components in the raw materials weakened and the depth of open pit mining
