Abstract: A device for collecting ionized metal from a liquid solution, such as silver from photographic or radiographic solutions, which is highly efficient in operation and convenient in use. Efficiency of the device results from a unique impeller/turbulator which, besides being adapted to pump liquid through the device, induces a relatively high state of turbulence in such flow that promotes electrolytic action. A cathode on which metal ions are deposited is formed of a flexible sheet of carbon-filled plastic that is low enough in cost to be conveniently disposable.

Abstract: A device for collecting ionized metal from a liquid solution, such as silver from photographic or radiographic solutions, which is highly efficient in operation and convenient in use. Efficiency of the device results from a unique flow path which induces vortex currents that promote increased electrolytic action. A cathode on which metal ions are deposited is formed of a configuration and composition that is sufficiently inexpensive to be considered disposable. Disassembly and reassembly of the device is accomplished with a minimum of effort and manipulative steps.

Abstract: A device for recovering metal from an aqueous bath generating metal ions, by means of an electrolytic process. The device includes a source of direct current and a non-conductive base plate adapted to be immersed in the aqueous bath. One face of the base plate has a conductive anodic surface layer thereon operatively connected to the direct current source for charging the anodic surface positively. The other face of the base plate has a conductive cathodic surface layer thereon also operatively connected to the direct current source for charging the cathodic surface negatively so that metal from the metal ion bath is plated onto the cathodic surface.
