Abstract

1344950 Producing aluminium PAR LEE ANDERSON CORP 18 Jan 1971 27628/73 Divided out of 1342991 Heading C7D A carbothermic method for reducing aluminium oxide comprises reacting the oxide with carbon or carbon source material in excess of stoichiometric requirements at temperatures above 600‹K in molten tin and maintaining the partial pressure of carbon monoxide over the reaction mixture below the equilibrium value for the reaction as the reduction takes place. After reaction the temperature of the mixture may be lowered, eg to 510-600‹K to precipitate aluminium while the tin remains liquid.
