An electrochemical cell is disclosed for eliminating and/or recovering dissolved metals from waste liquors or winning dissolved metals from waste solutions having a low concentration of such metals. The cell has a three dimensional electrode with a geometrical bed depth that is increased from the electrolyte inlet to outlet so that the bed depth increases along the flow direction corresponding to the concentration decrease within the cell. Thus, the geometrical bed depth is essentially equal to the effective bed depth at each point within the electrode where the electrochemical conversion takes place.
