摘要
介绍了国内铜渣的资源现状,分析了铜渣中铁的存在形式,综述了直接磁选法、高温氧化法、还原法以及湿法从铜渣中回收铁的工艺技术现状及存在的主要问题,并依据现有的能源结构,展望了煤基直接还原技术的发展前景。
The domestic copper slag resources are introduced. The forms of the iron in copper slag are analyzed. The process status of recovering iron from copper slags is reviewed, including direct magnetic separation, high temperature oxidation, reduction and hydrometallurgy extraction. The main problems of each method are expounded. The development prospect of the coal-based direct reduction based on the features of energy and resource is presented as well.
