摘　　要：随着国内铜资源需求量不断增加,精炼铜的生产量与消费量之间存在巨大缺口,废杂铜的回收利用成为解决铜资源紧缺的必要途径。废杂铜按铜品位常分为高、中、低3类,其中高品位废杂铜可通过直接利用或一段法等工艺进行回收,中低品位废杂铜则主要采用两段法、浮选和湿法等工艺回收。通过论述不同类别废杂铜的回收工艺,详细分析火法、湿法及浮选法处理废杂铜的实施案例,归纳总结了各种工艺的原理与优缺点。基于中国废杂铜回收现状进行了展望,若能完善废杂铜的分类标准和回收体系,可有效提升废杂铜资源的综合利用水平。With the increasing demand for domestic copper resources,there is a large gap between the production and consumption of refined copper,and the recycling of scrap copper has become a necessary way to solve the shortage of copper resources.Scrap copper can be divided into three categories according to copper grade,namely high,medium and low grade,in which the high-grade scrap copper can be recycled by direct utilization or one-stage process,while the medium and low grade scrap coppers are mainly recycled by two-stage process,flotation and hydrometallurgical process.The recycling process of different types of scrap copper was discussed in detail,and the principles,advantages and disadvantages of various processes were summarized by analyzing the implementation cases of pyrometallurgy,hydrometallurgy and flotation methods for scrap copper.Based on the current situation of copper scrap recycling in China,improving the classification standards and recycling system of copper scrap can effectively enhance the comprehensive utilization of scrap copper resources.
