An apparatus for recovering a conductive metal from a liquid which contains that metal, and a method for recovering that metal using that apparatus. The apparatus includes a generally closed non-metallic container defining a cavity, for containing the liquid. A first electrode is supported and affixed within the cavity. A second electrode is composed of a thin film applied to the inside surface of the container, the film including as its main constituent the same metal as that to be recovered from the solution. Finally, a power supply is electrically connected, positive to the first electrode and negative to the second electrode, thus causing the metal from the solution to be deposited on the film electrode, lining the inside surface of the container with the metal to be recovered. The disclosed method includes continuously circulating metal-containing liquid into the container and removing demetalized solution from the container. Because the container is disclosed to be constructed of material, such as plastic, which will not contaminate the metal during smelting, the entire container can be placed in a smelting furnace on completion of the demetallizing operation eliminating a messy and wasteful metal removal step.
