Abstract: A METHOD OF OPERATING A CELL OF AT LEAST 50 KA. FOR THE PRODUCTION OF ALUMINUM, COMPRISING CHOOSING THAT ANODIC CURRENT DENSITY WITH WHICH, WITH A DETERMINED ELECTROLYTE TEMPERATURE, A DETERMINED INTERPOLAR DISTANCE AND A DETERMINED THICKNESS OF THE ALUMINA COVERING ON THE ENCRUSTED SURFACE OF THE BATH, AS MUCH HEAT IS PRODUCED IN THE CELL AS THE CELL CAN CARRY AWAY AS LOSSES, AFTER DEDUCTION OF THE USEFUL AMOUNTS OF HEAT FOR THE DECOMPOSITION OF THE ALUMINA AND FOR HEATING OF THE RAW MATERIAL.

Abstract: PROCESS FOR THE ELECTROLYTIC RECOVERY OF ALUMINUM FROM A FUSED ALUMINA-CONTAINING BATH OF ALKALI ALUMINUM FLUORIDE IN WHICH THE FLUORIDE MELT IS KEPT IN DIRECT CONTACT WITH A MELT CONSISTING OF ELECTROLYTE HIGHLY CONCENTRATED IN ALUMINA AND SEPARATED FROM THE LIQUID CATHODIC ALUMINUM. THE ELECTROLYTIC CELL USED THEREFORE COMPRISES ONE OR MORE TROUGHS RESTING ON ITS BOTTOM AND PROVIDED FOR THE RECEPTION OF THE HIGHLY CONCENTRATED ELECTROLYTE.
