一、废杂铜已成为我国铜工业 的重要原料来源 我国既是铜资源较贫乏的国家又是世界上第二大铜消费国。1998～2001年精铜产量约占世界总产量的9％,产量增长率约为世界平均增长率的1.6倍;精铜消费量约占世界总消费量的12％,消费量增长率约为世界平均增长率的5倍。而解决资源缺乏和消费急增矛盾的方法则是大量进口铜原料,进口情况
I. Waste copper has become an important source of raw materials for China’s copper industry. China is not only the country with relatively poor copper resources, but also the second largest consumer of copper in the world. From 1998 to 2001, refined copper production accounted for about 9% of the world’s total output. The growth rate of production was about 1.6 times the world average growth rate; the consumption of refined copper accounted for about 12% of the world’s total consumption, and the growth rate of consumption was about the world. The average growth rate is 5 times. The solution to the problem of the lack of resources and the sharp increase in consumption is the large amount of imported copper raw materials.
