    Abstract: Wrought copper cathode starting sheets for use in the electrolytic production of copper made preferably by a continuous casting and rolling process are provided. Refined copper is melted in a shaft furnace and continuously cast preferably using a twin belt horizontal caster and straight line rolled to reduce the thickness of the casting by about 25% to 98% to produce a sheet having a thickness up to about 0.123 inch. The continuous sheet is cut after the rolling process from uncoiled sheet into discrete rectangular shapes suitable for use as a starting sheet, as a starting sheet blank or other metal sheet uses such as cladding and roofing.
