ALLOY AND ANODE FOR USE IN THE ELECTROWINNING OF METALS

IMPROVED ALLOY AND ANODE FOR USE IN THE ELECTROWINNING OF METALS A LEAD CALCIUM TIN ALLOY TO WHICH COBALT HAS BEEN ADDED IS DESCRIBED. THE ALLOY IS USEFUL IN THE FORMATION OF ANODES TO BE USED IN ELECTROV&NING CELLS. ELECTROWINNING CELLS CONTAINING THE COBALT ALLOYS ARE PARTICULARLY SUITED FOR ELECTROWINNING METALS, SUCH AS COPPER, FROM SULFURIC ACID ELECTROLYTES. THE COBALT-CONTAINING ANODES IMPROVE THE EFFICIENCY OF OXYGEN EVOLUTION AT THE ANODE DURING ELECTROWINNING AND REDUCE CORROSION OF THE ANODE.
