摘要: A multimonopolar cell for electrowinning aluminium by the electrolysis of alumina dissolved in a molten salt electrolyte, comprises electrode assemblies each having non-consumable anode and cathode both resistant to attack electrolyte respective product electrolysis. The (2) is preferably tubular form with an active surface (7) inside, made one or more rods (1) tubes placed middle between plate anodes, extending beyond bottom anode. area bigger than facing area. In use, assembly partly immersed vertically at slope (3) dipping layer (4) aluminum on bottom. Liquid formed during drips downflows oxygen evolved rises through escapes top Current supply aluminium.
