Study on Solution Line Corrosion of PbCaSn Anodes in Copper Electrowinning
Abstract
Lead alloys function effectively as oxygen-evolving anodes in copper SX-EW operations, and they are highly resistant to corrosion. However, the presence of an organic (from solvent extraction circuits) in the electrolyte seems to enhance solution line attack. Laboratory tests showed that lead is soluble in D2EHPA, Acorga and LIX 984 to a limited, yet measurable, degree. Lead alloys and various lead phases formed on the anode were tested to evaluate their effect on the corrosion process in organic media. Possible causes for anode corrosion and mechanisms responsible for their initiation are discussed.
