摘要
铜渣是炼铜、湿法炼锌等工业生产过程中产生的一种高硅、高铁工业废弃物,其有价组分繁多,是极具潜力的二次资源。本文结合近年来国内外最新研究进展介绍了铜渣中有价组分的提取回收现状,包括铜贫化回收、铁回收以及其他有价组分的回收;同时综述了利用铜渣制备玻璃陶瓷材料、建筑材料等高附加值产品的进展;总结了目前铜渣的利用状况并指出了仍存在的问题,展望了其应用发展前景。
Copper slag is a kind of high-silicon and high-iron industrial waste produced in the process of copper smelting and zinc hydrometallutgy.It has many valuable components and it is a potential secondary resource.Based on the latest research progress at home and abroad in recent years,the extraction and recovery of valuable components from copper slag,including copper dilution recovery,iron recovery and recovery of other valuable components have been introduced.At the same time,the progress of preparing glass ceramic matericals,building materials and other high value-added products with copper slag is reviewed,the utilization status of copper slag at present is summarized,the existing problems are pointed out,and the application prospect is forecasted.
