  • Process for separating electrodeposited metal in electrolytic refining
    Patent number: 5376239
    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.
    Type: Grant
    Filed: November 3, 1993
    Date of Patent: December 27, 1994
    Assignee: Mitsubishi Materials Corporation
    Inventors: Hideomi Saito, Saburo Tanaka, Akiyoshi Tatsui, Akira Yoshioka
