三、我国再生有色金属生产的现状及与国外的差距根据有色金属工业总公司的统计,我国1949～1983年再生有色金属的产量如下:(不包括直接追回利用的部分)再生铜150万吨,占精铜总产量543万吨的28%,再生铝9万吨,占铝总产量550万吨的1.6%;再生铅39万吨,占精铅总产量321万吨的12%;再生锌25万吨,占锌总产量325万吨的5%,和发达国家相比差距是很大的。我国再生有色金属的生产,各个时期的发展是不平衡的,大体上可分成
Third, the current status of China’s renewable non-ferrous metals production and the gap with foreign countries According to the non-ferrous metals industry Corporation statistics, China’s production of recycled non-ferrous metals from 1949 to 1983 are as follows: (excluding direct recovery of the use of recycled copper 1.5 million tons , Accounting for 28% of the total refined copper output of 5.43 million tons, 90,000 tons of recycled aluminum, accounting for 1.6% of the total aluminum output of 5.5 million tons; recycled lead of 390,000 tons, accounting for 12% of the total refined lead output of 3.21 million tons; 250,000 tons, accounting for 5% of the total zinc output of 3.25 million tons, compared with the developed countries, the gap is great. China’s renewable non-ferrous metal production, the development of each period is not balanced, can be divided into
