<p>An electrolytic cell (2) for the recovery of silver from a photographic fixer solution is of generally cylindrical configuration. The cell has a screw-on lid (8) that carries the disposable cathode of the cell. Inlet (20) and outlet (18) for the solution are at the bottom of the cell. The anode (16) is tubular and extends upwardly from the outlet at the base of the cell towards the lid. The cathode is easily replaced, together with the lid, and flow through and the dimensions of the cell are arranged to avoid entrapment of gas therein. <IMAGE></p> |
