Abstract

1345943 Producing aluminium by fusion electrolysis SWISS ALUMINIUM Ltd 30 Nov 1971 [1 Dec 1970] 55588/71 Heading C7B An electrolytic cell for production of Al from Al 2 O 3 in a molten F bath is operated by increasing the current intensity only so far as is necessary to make up for the missing useful energy consequent on the reduction of the duration and/ or frequency of the anode effects.
