title = "Lead anodes performance in nickel electrowinning",
abstract = "Lead and its alloys are proper candidates for anodes in electrowinning processes mainly because they are insoluble in the leach solutions and relatively cheap. However, the annual cost of corrosion problems associated with these anodes is millions of dollars. In this study lead-silver and lead-calcium anodes were tested under typical nickel electrowinning conditions and the effect of chloride on the corrosion performance of the anode materials was investigated. Corrosion rates of the anodes were calculated using the discharge plateau (reduction of lead dioxide to lead sulfate) after galvanostatic experiments. It was found that lead calcium anodes have the highest corrosion rate both in the presence and absence of chloride. Surface morphology of the electrodes was studied using SEM and the corrosion products were characterized using XRD.",
