“…There are conflicting reports as to whether tin enhances or inhibits hydrogen evolution [38,35]. While As (III) had no effect on the current efficiency and does not alter deposit morphology or orientation, the presence of small concentrations of As (V) (less than 5 mg/1) are detrimental, causing changes in morphology and orientation and a dramatic decrease in current efficiency [39]. The presence of either glue or antimony or both in solution further aggravates the effect of As (V).…”

The removal of cobalt from zinc electrolyte has been a focus of electrometallurgical research for over 20 years. This survey reviews the literature on cobalt cementation as well as zinc electrowinning and hydrogen evolution in the interest of characterizing the factors which are important in cobalt cementation by zinc dust and developing an improved purification process. The effect of speciation, the solubility of zinc hydroxide and zinc sulfate, temperature, pH, and the concentrations of reacting species, impurities, and catalytic agents are all investigated.
