由于采出的有色金属矿石含有多种有用成分,但有色金属的富集程度较低(通常只有百分之几,万分之几甚至十万分之几的含量),因而有色冶金工业的原料综合利用具有极为重要的意义。目前,有色冶金生产要求每年开采20多亿吨矿石。有色冶金多年的实践说明,综合利用矿物原料所涉及到的一系列重大问题既是复杂的科 As a result of the mining of non-ferrous metal ore contains a variety of useful components, but the non-ferrous metals enrichment is low (usually only a few percent, a few thousandths or even a few thousandths of a few), and thus non-ferrous metallurgy industry synthesis Use is of great importance. At present, non-ferrous metallurgy production requires mining more than 2 billion tons of ore each year. Non-ferrous metallurgy years of practice shows that the comprehensive utilization of mineral raw materials involved in a series of major issues both complex subjects
