| Abstract |
Crude Zinc metal was electrorefined using electrolytic cell which consists of two compartments separated by a barrier that is immersed in a shallow pool of zinc amalgam without reaching the cell bottom. The amalgam, agitated with stirrer, acts as a cathode on one side and an anode on the other side. ZnSO₄ solution buffered with acetate was used as the refining solution. The current efficiency was 99.0% at pH 4.5. The electrorefining by using 99% Zn resulted in obtaining>5-9s. |
