在十种常用有色金属中 ,铜年产量仅次于铝居第二位。由于铜所具有的许多优异性能 ,故在用途方面决定了它不可能为其它金属或其它材料所全部取代。我国是一个 1 2亿多人口的国家 ,经济与社会发展对铜的需求日益增长。但由于我国的铜资源严重短缺 ,长期以来一直靠进口以弥补缺口。为解决这一矛盾 ,我国从事有色金属生产和回收利用的各个方面都做出了巨大的努力。从近年来看 ,在开发利用废杂铜方面 ,我国一直保持了较快的发展势头。本期发表中国有色金属工业再生资源公司所属的天津大通铜业有限公司的综述性文章 ,该文简要地综述了中国的废杂铜资源现状和再生铜的回收与利用的技术状况 ,对地区间的市场竞争态势也作了客观的分析。
Among the 10 commonly used non-ferrous metals, the annual output of copper is second only to that of aluminum. Due to the many excellent properties copper has, it has been determined, in terms of usage, that it can not be completely replaced by other metals or other materials. China is a country with a population of more than 1.2 billion and the demand for copper from economic and social development is on the rise. However, due to the serious shortage of copper resources in our country, the country has long relied on imports to make up for the gap. To solve this contradiction, China has made tremendous efforts in all aspects of non-ferrous metal production and recycling. In recent years, our country has maintained a relatively rapid momentum of development in the development and utilization of scrap copper. In this issue, a review article of Tianjin Datong Copper Co., Ltd., a subsidiary of China Nonferrous Metals Industry Renewable Resources Corporation, is presented. This paper briefly reviews the status quo of scrap copper resources in China and the technical status of recovery and utilization of recycled copper, The market competition situation also made an objective analysis.
