The present invention aims to provide a zinc electrowinning anode capable of inhibiting manganese compound deposition on the anode and a cobalt electrowinning anode capable of inhibiting cobalt oxyhydroxide deposition on the anode. The zinc electrowinning anode according to the present invention is a zinc electrowinning anode having an amorphous iridium oxide-containing catalytic layer formed on a conductive substrate, and the zinc electrowinning method according to the present invention is an electrowinning method using that electrowinning anode. Also, the cobalt electrowinning anode according to the present invention is an electrowinning anode having an amorphous iridium oxide or ruthenium oxide-containing catalytic layer formed on a conductive substrate, and the cobalt electrowinning method according to the present invention is an electrowinning method using that electrowinning anode.
A zinc electrowinning anode for use in zinc electrowinning, comprising a conductive substrate and a catalytic layer formed on the conductive substrate, wherein the catalytic layer contains amorphous iridium oxide.
A cobalt electrowinning anode for use in cobalt electrowinning, comprising a conductive substrate and a catalytic layer formed on the conductive substrate, wherein the catalytic layer contains amorphous iridium oxide or amorphous ruthenium oxide.
