ABSTRACT:
The invention relates to an electrowinning cell for extracting metals in powder form from solutions, and simultaneously oxidizing the solution. The cell is characterized by radially extending electrodes comprising mutually alternating anodes and cathodes; by a diaphragm which delimits separate anode and cathode chambers, of which the cathode chamber forms an outer space; and a stirring means arranged in the anode chamber and operative to ensure a large flow of electrolyte across the anode surfaces. The base of the cathode chamber is preferably conical in shape.
