摘　　要：废锌极板经连续循环浸出-电积锌粉-制作锌阳极板的工艺是可行的。其条件为：浸出介质为氢氧化钾溶液、浓度6～8mol／L、电解电流密度18002000A／m^2，保持溶液中Zn^2＋浓度20～25g／L，电解温度35℃，刮锌粉间隔时间1～2h。所得锌粉放电活性较好，适合作为锌-空气电池用。It is feasible to deal with depleted pole plate of zinc by continuous cycle leaching- electrowinning- making positive plate of zinc. The optimum conditions were determined by laboratory tests as follows： KOH 6-8 mol/L, the density of cathode current 1 800-2 000 A/m^2 , Zn^2＋ 20-25 g/L, 35℃, time interval of scraping zinc-powers 1-2 h. Zinc-powers is better on activity of discharge and is fit for making zinc air batteries.
