【Abstract】 Electrorefinement of hot galvanizing slag in ZnCl 2 NH 4Cl electrolyte is a new technology. This paper mainly studies the influence of parameters such as current density, composition of electrolyte, temperature, and electrolysis period on the actual electrorefining processes. It is demonstrated that the optimal electrorefining conditions are [Zn 2+ ]=40 g/L, =250 g/L, D k =250 A/m 2, t =35 ℃. Additionally, DC consumption and other indexes also change with the increase of Fe content in the anode.更多还原
