摘要
再生有色金属的生产具有低投资、低能耗、低成本、低污染和工艺较简单的特点。近几年我国的再生有色金属工业得到了较快的发展 ,尤其是在无污染湿法冶金处理方面 ,研究成功了一些新的回收、分离工艺 ,并建成了一批中小规模的工业生产厂。以铜、铝、铅、锌四种常用金属和镍、钴为例 ,介绍中国再生有色金属的生产现状及进展情况 ,指出中国再生有色金属的回收还需要做大量的工作。建议强化再生有色金属资源的收集。
The production of secondary non ferrous metals(SNM)is characterized by low investment,energy consumption and cost,less pollution as well as rather simple technology In the past years,the SNM industry has made relevantly rapid progress in China Especially in the field of clean hydrometallurgical treatment certain novel technologies for recovery and separation have successfully been elaborated,and some of medium and small commercial plants established On the basis of Cu,Al,Pb,Zn and Ni,Co,the status and progress of SNM industry in China is described, there are a lot of work to do for salvaging waste metals It is recommended that SNM resource collecting and classifying should be strengthened and the research on new technologies for recovering such metals should be supported
