摘要：Finely divided particles of alumina are electrolytically reduced to aluminum in an electrolytic reduction vesl having a plurality of vertically dispod, non-consumable anodes and a plurality of vertically dispod, dimensionally stable cathodes in cloly spaced, alternating arrangement with the anodes. A horizontally dispod, gas bubble generator is located at the vesl bottom, underlying the cathodes and the spaces between each pair of adjacent electrodes. The vesl contains a molten electrolyte bath compod of (1) NaF+Alf.sub.3 eutectic, (2) KF+ AlF.sub.3 eutectic and (3) LiF. The alumina particles are maintained in suspension in the molten electrolyte bath by rising gas bubbles generated at the anodes and at the gas bubble generator during the reduction process.
