Abstract

The electrowinning of zinc is sensitive to metallic Impurities especially from the points of view of current efficiency and purity of the deposit. Moreover, the effect of impurities in combination is in general detrimental to electrolysis than of single impurity, The organic addition agents are known to influence the nature of deposit and current efficiency, In this context, studies have been made with regard to the influence of addition agents like fish glue, avitone, gelatin and sodium lignin sulphonate, Among the additions studied avitone shows promise from the point of view of current efficiency, The influence of metallic impurities like nickel, cobalt and antimony individually and in combination has also been investigated
