Abstract:
A closed loop electrochemical process of recovery of high-purity lead uses continuous formation of adherent lead on a cathode from an electrolyte that is used to dissolve desulfated lead paste. Preferred cathodes include aluminum containing cathodes that are operated in methane sulfonic acid to produce a micro- or nanoporous mixed matrix metallic composition and lead dioxide formation at the anode is avoided using appropriate anode configurations or operating conditions
