摘　　要：ZnCl2 NH4Cl溶液体系中进行热镀锌渣的电解精炼是处理热镀锌渣的全新工艺。该文重点研究杂质元素Fe、Ni、Sn等对锌电解精炼效果诸如电流效率、直流电耗、阴极锌品位、阴极沉积物形貌的影响。同时进行了锌粉置换除铁的效果分析。Eletrorefining of hot galvanizing slag in ZnCl2NH4Cl electrolyte is a completely new technology.It is demonstrated that impurities of Fe,Ni and Sn have influence on the electrorefining results such as current efficiency,direct current(DC)consumption,impurities content in cathodic zinc and the cathodic zinc appearance.Additionally,the effects of Fe replacement by zinc are also studied.
