有色金属良好的循环再生利用性能,不但在节能减排中效益显著,而且为经济的可持续发展提供了有效的资源保障,在国民经济中发挥了积极的作用。发展再生有色金属产业,是有色金属工业发展的重要趋势。再生资源前景广阔发展再生有色金属产业,多次循环利用有色金属,既保护原生矿产资源,又节约能源、减少污染。据测算,与原生金属生产相比,每吨再生铜、再生铝、再生铅分别相当于节能1054千克标煤、3443千克
The good recycling performance of non-ferrous metals not only has significant benefits in energy conservation and emission reduction, but also provides an effective resource guarantee for the sustainable economic development and plays an active role in the national economy. The development of non-ferrous metal industry is an important trend in the development of non-ferrous metal industry. Renewable resources, promising prospects for the development of renewable non-ferrous metals industry, many non-ferrous metals recycling, both to protect primary mineral resources, but also save energy and reduce pollution. It is estimated that, compared with the production of primary metals, recycled copper, recycled aluminum and recycled lead are equivalent to energy saving of 1054 kilograms of standard coal and 3443 kilograms respectively
