Experimental result are presented for the preparation of zinc metal from Zinc Sulphate solution using electrochemical process. Laboratory cell which equipped with lead anode and aluminum cathode, was designed and utilized to obtain experimental result which was necessary for proceeding of the designated objective of this work. In the present experiment about 121 gm.-Zn / L solution was electrolyzed batch-wise at a current density rang 0.03-0.1 Amp./cm2 at a temperature of 40 to 45 ◦C. The effect of electrolytes concentration and the final concentration of zinc ions and sulphuric acid formed were also tested. The current efficiency of about 92% was obtained for 75% zinc ions conversion, at optimum condition mainly current density of 0.08 Amp./cm2 ,temperature of about 40 ◦C. The above current efficiency is similar to that reported in related studies.
