ANODE FOR ELECTROWINNING METAL

PURPOSE:To enable a drop in anode potential while reducing the amount of Ag, by adding a specified amount of Ca to a Pb-Ag alloy. CONSTITUTION:This anode for electrowinning metal is made of an alloy having a composition consisting of 0.2-2.0wt% Ca, 0.2-1.2wt% Ag and the balance Pb with inevitable im...

Beschreibung
Zusammenfassung:	PURPOSE:To enable a drop in anode potential while reducing the amount of Ag, by adding a specified amount of Ca to a Pb-Ag alloy. CONSTITUTION:This anode for electrowinning metal is made of an alloy having a composition consisting of 0.2-2.0wt% Ca, 0.2-1.2wt% Ag and the balance Pb with inevitable impurities. By the composition the contamination of Zn or other metal deposited on a cathode with Pb can be reduced, and the anode potential can be dropped while reducing the amount of Ag. The anode is used to electrowinning metal in an acidic aqueous soln. of sulfuric acid.
