ABSTRACT:
An electrolytic cell comprising a rectangular tank divided into a plurality of adjacent compartments by a plurality of spaced apart parallel electrode plates. The outboard electrodes may form one pair of the opposite tank walls. Alternate electrodes are of opposite polarity. The intermediate electrodes terminate short of the tank ends so that the slurry or solution may pass around both ends of the electrode. An agitator is mounted in each compartment. The agitators are shaped and positioned to direct a predetermined volume of slurry against each electrode, the amount being directed against the cathode and anode respectively may be equal or unequal depending on the metal being recovered and the chemical reaction required at the electrode. Strips of non-conductive material are arranged in the cell in spaced overlapping relationship with the peripheral side and bottom edges of each side of each cathode thereby blocking straight line current flow between the cathode edges and the closest anode area while defining a narrowed passage for directing slurry past such edges in a scrubbing action. The agitators and the associated mounting means can be adjusted to vary the volume of flow against the electrodes. Lifting fins are provided on the agitators for maintaining solids in suspension. An inlet and outlet are provided on opposite sides of the tank and the spaces around the ends of the intermediate electrodes and between the cathodes and the non-conductive strips are selected so that reciprocation of the agitators enhances flow of slurry through successive chambers between the inlet and outlet.
