随着国民经济的日益发展,有色金属的应用范围逐渐扩大,有色金属的消耗量也随之增长。目前,我国有色金属的生产还是一个薄弱环节。铜、铝、铅、锌等常用有色金属一直不能自给,长期以来依靠进口。铜板、铝薄板、铝箔、青铜带、黄铜带等短线产品仍然十分紧缺。目前,我国在资金不足、矿产资源品位低、能源供应紧张的情况下,如何使有色金属的产量迅速增长,以满足国民经济日益发展的需要,这是有色冶金工作者义不容辞的任务。在有色金属的冶炼和加工中,产生了大量的有色金属废料和废件,充分回收和利用好这些有色金属废料和废件是增加有色金 With the continuous development of the national economy, the application range of nonferrous metals is gradually expanding, and the consumption of nonferrous metals also increases. At present, the production of non-ferrous metals in China is still a weak link. Copper, aluminum, lead, zinc and other non-ferrous metals have been unable to self-sufficiency, has long relied on imports. Copper, aluminum sheet, aluminum foil, bronze tape, brass tape and other short-term products are still very scarce. At present, under the conditions of insufficient funds, low grade of mineral resources and tight energy supply, how to rapidly increase the output of nonferrous metals to meet the needs of the growing national economy is an unshirkable task for nonferrous metallurgy workers. In the non-ferrous metal smelting and processing, resulting in a large number of non-ferrous metal scrap and scrap, full recovery and utilization of these non-ferrous scrap and scrap metal is to increase non-ferrous
