金属矿产资源是一次性资源,具有不可再生的特点。充分利用矿产资源与尽量回收其伴生有益组份问题愈来愈为人们所重视。尤其在资源短缺,能源紧张的情况下,搞好矿产综合利用更有其重要意义.欲提高综合利用水平,必须加强矿石物质组份研究工作。众所周知,矿产资源是地球中各种成矿物质通过不同地质作用,由分散变为富集而形成的.由于地质作用的多次迭加和改造,在自然界中一种金属矿产独立产出的情况很少,多数是几种矿产或几种有益组份同时并存,构成所谓复合矿石或复合矿床.据姚长山等(1982)统计某些有色金属矿石其伴生组份具有重要的经济价值,有的伴生组份价值超过了主金属的价值(见附表)
Metal mineral resources is a one-time resource, with non-renewable characteristics. More and more attention has been paid to the issue of making full use of mineral resources and recycling their associated beneficial components. Especially in the case of shortage of resources and energy shortage, it is more important to improve the comprehensive utilization of mineral resources.If it is necessary to improve the level of comprehensive utilization, we must strengthen the research work on the composition of ore components. It is well-known that mineral resources are formed by the diversification and enrichment of various ore-forming materials in the earth through different geologic functions. Due to the multiple superimposition and transformation of geological effects, a situation in which metal minerals are produced independently in nature Few, most of them are several kinds of minerals or several beneficial components co-exist at the same time, forming the so-called composite ore or composite deposit.According to Yao Changshan et al (1982) statistics of some non-ferrous ore ore with associated components of important economic value, Component value exceeds the value of the main metal (see attached table)
