Titanium-lead anode for use in electrolytic processes employing sulfuric acid

摘要

An anode for use in electrolytic processes with an electrolyte containing sulfuric acid. The anode comprises a valve metal substrate, a lead or lead alloy antipassivation layer in contact with the valve metal substrate, and a lead ruthenate or lead iridate catalyst in surface contact with the lead or the lead alloy. Also disclosed are methods for employing the anode in electrowinning processes as well as a process for operating an electrolytic cell.
