Abstract: A process for producing aluminum, including electrolytically decomposing alumina to aluminum metal in an electrolyte bath between a carbon anode and a cathodic interface formed between metal and the electrolyte bath, the bath A. CONSISTING ESSENTIALLY OF Al2O3, NaF, and A1F3, and B. HAVING A WEIGHT RATIO NaF to A1F3 up to 1.1:1, WHILE MAINTAINING THE BATH AT AN OPERATING TEMPERATURE EFFECTIVE FOR PREVENTING BATH CRUSTING IN INTERFACIAL AREAS BETWEEN BATH AND ALUMINUM METAL, WHILE ENCLOSING THE TOP OF THE CELL FOR KEEPING THE SURFACE OF THE BATH MOLTEN, AND WHILE FEEDING ALUMINA A. SUBSTANTIALLY CONTINUOUSLY ONTO THE MOLTEN BATH SURFACE, B. THE ALUMINA HAVING A WATER CONTENT EFFECTIVE FOR PREVENTING ANODE DUSTING, C. THE CARBON ANODE BEING EXPOSED TO THE GASEOUS WATER EVOLVED FROM THE ALUMINA, WHEREBY ANODE DUSTING IS PREVENTED.
