铜冶炼技术虽已被人类掌握数千载,但铜冶炼废弃物处理仍是当前亟待解决的问题,铜渣富含氧化铁、二氧化硅、氧化钙和氧化铝,从铜渣中回收金属对缓解金属资源短缺和降低环境污染具有重要意义。介绍了物理与化学方法回收铜与其他重金属技术,如浮选、火法冶金和湿法冶金,并对当前所用技术研究与应用进行了总结,对技术优缺点及使用范围进行了比较。阐述了铜渣主要的利用途径,包括作为建筑材料与路基材料,旨在促进环境可持续发展。分析了铜渣性质在该应用领域的优势及在新领域中的应用前景。铜渣废料的回收与再利用具有循环经济价值,如增加关键金属供应,降低混凝土成本,减少环境危害等。该研究为铜渣固废处理提供了一条路线图。
Although copper smelting technology has been mastered by humans for thousands of years, the treatmentof waste generated by copper smelting remains a pressing issue. Copper slag is rich in iron oxide, silica, calcium oxide,and alumina. Recovering metals from copper slag is of great significance for alleviating metal resource shortages andreducing environmental pollution. Physical and chemical methods for recovering copper and other heavy metals wereintroduced, such as flotation, pyrometallurgy, and hydrometallurgy. Current research and application of these technologieswere summarized, and their advantages, disadvantages, and applicable scopes were compared. The main utilizationpathways of copper slag were described, including its use as construction materials and subgrade materials to promoteenvironmental sustainability. The advantages of copper slag properties in these applications and potential new areas ofuse were analyzed. The recovery and reuse of copper slag waste offer benefits in a circular economy, such as increasingthe supply of critical metals, reducing concrete costs, and minimizing hazards to the environment. This study provides aroadmap for the treatment of copper slag solid waste.
