ABSTRACT:
A method and apparatus for electrolytically preparing in an electrolytic cell metal, preferably zinc, in pulverulent form from a compound of the metal, for example, zinc oxide, in an aqueous ionized solution, for example potassium hydroxide of a concentration of 100 to 800 g/l, the solution preferably containing 10 to 350 of zinc per liter. The cathode at the bottom of the electrolytic cell comprises a layer of the same pulverulent metal, for example zinc, into which a grid cathode current input is introduced, the cathode current applied being sufficient to prevent the formation of metal in continuous form, preferably between 8 and 18 A/dm.sup.2. The anode is disposed in the cell above the cathode. New solution is injected about the lower periphery of the cell so as to set the solution and pulverulent metal is turbulent suspension. The suspension is drawn off by a pump and allowed to settle in a settling tank the pulverulent metal being removed by a conveyor screw, the solution spilling over into a storage tank and then pump back to the cell and reintroduced by the injectors. A plurality of cells may be arranged in a stack or columns, operating sequentially, and utilizing the same settling tank, associated pumps, and other auxiliary equipment.
