摘要
铜渣中除了铜还赋存有铁、铅、锌等有价金属资源,由于铜渣自身物化性质及技术、成本限制,铁、铅、锌的回收一直未有成熟工艺。国内外研究人员对此开展了多方向研究,通过调研分析现有铜渣中铁的经济回收,以及火法或湿法回收渣中铅、锌的研究现状及存在问题,对铜渣中有价金属资源的综合回收前景进行展望。
In addition to copper,copper slag also contains valuable metal resources such as iron,lead,and zinc.Due to the physical and chemical properties of copper slag,and technical and cost constraints,the recovery of iron,lead,and zinc has not been mature.Researchers at home and abroad have carried out multi-directional research on this.The article analyzes the current economic recovery of iron in copper slag and the research status and existing problems of the recovery of lead and zinc in slag by pyrometallurgical or hydrometallurgical methods.The comprehensive recovery of valuable metal resources in the copper slap is prospected.
