我国的金属资源十分丰富,品种相当齐全。已探明10种有色金属储量13亿吨,钨、锡、锑、锌等的储量,均占世界第一位。建国以来,国家为发展有色工业提供了巨额投资,建成了一大批不同规模的矿山,形成了年产矿石约6500万吨的综合生产能力;有色矿石的产量以年乎均14.7％的速度增长;矿山产品质量有很大提高,1980年铜精矿品位达到21.60％,去年上半年又提高到22.90％,赶上了国际水平;矿山的生产技术有很大进步,逐步形成了一整套适合我国矿产资源特
China’s metal resources are very rich, a full range of varieties. Has proven 10 kinds of non-ferrous metals reserves of 1.3 billion tons, tungsten, tin, antimony, zinc and other reserves, both in the world. Since the founding of New China, the state has provided a huge investment for the development of nonferrous metals industry and built a large number of mines of various sizes, forming an integrated production capacity of about 65 million tons of ore annually. The output of nonferrous ore has been growing at an average annual rate of 14.7% The quality of mine products has greatly improved. In 1980, the grade of copper concentrates reached 21.60% and reached the level of 22.90% in the first half of last year, catching up with international standards. Great progress has been made in the production technology of mines to gradually form a set of products suitable for China’s mineral resources Resources special
