Abstract: A process for separating an electrodeposited metal from a cathode plate in electrolytic refining is disclosed. The cathode plate on which the metal is electrodeposited is first held. Then, heated air is blown toward the cathode plate and the electrodeposited metal thereon. As a result, the electrodeposited metal is separated from the cathode plate. An apparatus for carrying out the same process is also disclosed. The apparatus includes a separating furnace, a holding assembly, and a device for introducing heated air into the separating furnace. The holding assembly is attached to the separating furnace for holding the cathode plate in the furnace. The heated air-introducing device introduces heated air, blowing it against the cathode plate, whereby the electrodeposited metal is separated from the cathode plate.
