有色金属是国民经济建设的重要原材料和物质基础,也是重要的战略物资。随着经济建设的发展,有色金属的应用领域不断扩大,用量也在急剧增加。由于有色金属用量的增加和矿产资源的减少,有色金属的再生已受到高度重视。目前,在消费的有色金属中,再生金属的比例很高。然而,有色金属再生工业的迅速发展,也使一些有色金属的再生资源越来越紧张,特别是常用的铜、铅、锌、镍、钴、锡等金属的再生资源已不能满足再生工业的需要,开发新的金属再生
Non-ferrous metal is an important raw material and material basis for the national economic construction as well as an important strategic material. With the development of economic construction, the application fields of nonferrous metals are constantly expanding, and the amount of consumption is also rapidly increasing. Due to the increase of non-ferrous metal consumption and the decrease of mineral resources, the non-ferrous metal regeneration has received great attention. At present, the proportion of recycled metals in the consumption of non-ferrous metals is high. However, the rapid development of non-ferrous metal recycling industry has also made some non-ferrous metal resources more and more nervous. In particular, the regenerative resources of commonly used metals such as copper, lead, zinc, nickel, cobalt and tin can not meet the needs of the recycling industry , Develop new metal regeneration
