We studied the effects of current densities on the anodic corrosion of pure leadand silver-containing lead anodes in electrolytic zinc deposition. The results were as follows: With pure lead anode, the lead content of zinc deposit was not materially affected by the current density up to about 4A/dm², but when raised to6-10A/dm², it was considerably increased. The lead contents of zinc deposits at the current density above 6A/dm² decreased rapidly with the increasing silver content of lead anode up to about 0.5%; above this its change became practicallynegligible. The amount of anode slime behaved like this. The anode potential decreased gradually with the increase of silver content of the lead anode.
