我国再生金属资源利用潜力研究及对策

Study and Countermeasures on Potential of Utilizing Regenerated Metal Resources in China

建国以来，我国再生金属回收利用为基础材料工业提供了大量的原料，减轻了固体废弃物对环境的污染。但是我国的再生技术工艺和加工设备均较落后，金属的再生率低，与西方发达国家相比存在较大的差距。我国对废旧钢铁、铜、铅的回收利用相对较好，废旧铝、锌及其它金属的回收利用水平较低。

Since the foundation of P. R. C., the regenerated metal resources have supplied a large amount of raw material for basic material industry, and then pollution of the environment has been mitigated owing to reduction of solid wastes. We do a good job in recycling of wastes of iron and steel, copper and lead but we have much to do in recovery of wastes of aluminum and zinc and the like. In general, great potential of utilizing regenerated metal resources does exit, and we must pay efforts on improvement of regenerating technology and equipment which backwards in comparison with that in advanced country.
