Abstract

A process for the production of aluminum by the electrolysis of anhydrous aluminum chloride produced by the carbochlorination of alumina in a molten salt bath containing at least one alkali metal and/or alkaline-earth metal halide, comprising carrying out the carbochlorination of the alumina and electrolysis of the aluminum chloride in a continuous production loop using the molten salt bath emanating from carbochlorination as the electrolysis bath and the molten salt bath emanating from electrolysis as the carbochlorination bath.
