ABSTRACT:
A process for the production of metals by the electrolysis of metal compounds dissolved in a molten electrolyte, in particular for the production of aluminum from aluminum oxide. The electric power is passed through a multi-cell furnace with at least one inconsumable bi-polar electrode, made of electrode materials which are compatible with one another. The anions, in particular, the oxygen ions of the dissolved metal compounds have their charges removed on the surface of the electron conductive ceramic oxide anode and the metal ions, in particular the aluminum ions on the surface of the cathode which is made of another material than that used for the anode surface.
