摘　　要：分析了锌片中铅、铜、铁、镉、锡、铝的来源,采取改善阳极板质量、阳极镀膜、阳极拍平周期优化、电解液总酸根控制、槽间垫板优化等措施,Pb≤15 g/t,Cu≤4 g/t,杂质总和≤30 g/t的锌片产量提升至40%以上。This paper analyzes sources of lead(Pb),copper(Cu),iron(Fe),cadmium(Cd),tin(Sn),and aluminum(Al)in zinc cathodes.By improving the quality of the anode plate and the anode coating,optimizing the duration of anode flattening,controlling the total sulfate content in the electrolyte,and optimizing the copper bar support,it was possible to achieve concentrations of Pb≤15 g/t and Cu≤4 g/t in the zinc cathode.As a result,the yield of zinc cathodes with total impurities≤30 g/t increased by more than 40%.
