在现代条件下,合理地和综合地利用采出的矿产具有重大的国民经济意义。这是由矿物原料的开采量日愈增加和矿产的特点所决定的。矿产与其它自然资源不同,它是有限的和不可再生的。充分回收和综合利用矿物原料,可在不增加新投产矿床的条件下巩固工业的矿物原料基地,并因节约一次性投资和日常开支以及提高劳动生产率而提高社会生产的经济效益。
Under modern conditions, the rational and comprehensive utilization of the mined minerals has great national economic significance. This is determined by the increasing exploitation of mineral raw materials and the characteristics of minerals. Unlike other natural resources, minerals are finite and non-renewable. The full recovery and comprehensive utilization of mineral raw materials will consolidate the industrial base of mineral raw materials without adding new production deposits and increase the economic benefits of social production by saving one-time investment and daily expenses and raising labor productivity.
