摘　　要：铜渣中铁元素主要以玻璃相、铁橄榄石和磁铁矿形式存在,铜以铜锍形式分布其中。通过热力学理论计算和试验分析可知,氯化焙烧方法可以对铜渣进行选择性氯化,即铜以氯化物形式挥发,铁留在渣中,达到铁铜分离的目的。The iron element of copper slags exists as the form of glass phase, fayalite, and magnetite, and the copper element is distributed as the form of copper. Through theoretical calculations and experimental thermodynamic analysis, it shows copper slag can be selectively chloridized by chlorination roasting method, namely copper is volatile in the form of chloride and iron is left in the slag, which achieves the purpose of the separation of Fe and Cu.
