当前,再生有色金属产业已成为缓解我国矿产资源供应短缺矛盾、促进有色行业节能减排、发展国民经济的重要措施。例如,再生铜、铝、铅、锌综合能耗分别只是原生金属的18%、45%、27%和38%;生产每吨分别可以节约相应矿石资源量380吨、20吨、128吨、52吨和标准煤1 054千克、3 443千克、659千克、950千克。预计到2020年,我国再生有色金属产业将不断发展壮大,产品总量将超过2 000万吨,工业产值将接近1万亿元。虽然如此,2013年再生有色金属产品产量却出现小幅下降,企业经济效益明显下滑,新建项目
At present, the regeneration of non-ferrous metal industry has become an important measure to alleviate the contradiction between the shortage of mineral resources in our country, promote energy-saving emission reduction in the non-ferrous industry and develop the national economy. For example, the comprehensive energy consumption of recycled copper, aluminum, lead and zinc is only 18%, 45%, 27% and 38% of that of primary metals respectively; the corresponding ore resources can be saved by 380 tons, 20 tons, 128 tons and 52 tons respectively 1 054 kg and 3 443 kg, 659 kg and 950 kg of standard coal. It is estimated that by 2020, China’s regenerative non-ferrous metal industry will continue to grow and develop, with a total product output of over 20 million tons and an industrial output value of nearly 1 trillion yuan. Nonetheless, the output of non-ferrous metal products rebounded slightly in 2013, and the economic benefits of enterprises dropped significantly. The newly-built projects
