ANODE FOR USE IN ZINC AND COBALT ELECTROWINNING AND ELECTROWINNING METHOD

摘要

The present invention aims to provide a zincelectrowinning anode capable of inhibiting manganese compounddeposition on the anode and a cobalt electrowinning anode capableof inhibiting cobalt oxyhydroxide deposition on the anode.The zinc electrowinning anode according to the presentinvention is a zinc electrowinning anode having an amorphousiridium oxide-containing catalytic layer formed on a conductivesubstrate, and the zinc electrowinning method according to thepresent invention is an electrowinning method using thatelectrowinning anode. Also, the cobalt electrowinning anodeaccording to the present invention is an electrowinning anodehaving an amorphous iridium oxide or ruthenium oxide-containingcatalytic layer formed on a conductive substrate, and the cobaltelectrowinning method according to the present invention is anelectrowinning method using that electrowinning anode.
