Abstract
Electrolytic solutions containing organic additive(s) selected from a described class of additives (e.g., 4,6-dihydroxypyrimidine) reduce overall applied electrical potential of electrolytic cells and/or reduce gas formation at the anode(s) or increase copper production rate. Benefits include reducing overall power consumption and reducing acid mist during electrolytic processes.
