ANODE AND CATHODE ON INSULATOR

摘要

An electrolytic apparatus is disclosed for recovering a metal from a solution in which the metal is present in ionic form. In the preferred embodiment, the apparatus includes an elongated strip of plastic film coated on both sides thereof with conductive coatings to form anodic and cathodic surfaces. The film strip is located between two end plates to form a cell. The strip is formed into a spiral or helix so as to place the anodic surface opposite the cathodic surface. The cell is mounted within a canister and fluid passageways are provided to enable metal ion-containing solution to pass through the helical cell. Electrical leads are provided to equally distribute the plating current throughout the cell.
