Claims (2)

1. Способ получения алюминия путем термической обработки оксида алюминия углеродом, дальнейшего получения парообразного субгалогенида алюминия и его последующего вывода из зоны реакции, охлаждения и выделения металлического алюминия, отличающийся тем, что термическую обработку оксида алюминия углеродом ведут в расплаве оксида алюминия с солями галогеноводородных кислот и в присутствии тригалогенида алюминия, получая парообразный субгалогенид алюминия за одну операцию.1. The method of producing aluminum by heat treatment of aluminum oxide with carbon, further obtaining a vaporous aluminum subhalide and its subsequent withdrawal from the reaction zone, cooling and separation of aluminum metal, characterized in that the heat treatment of aluminum oxide with carbon is carried out in a melt of aluminum oxide with salts of hydrohalic acids and in the presence of aluminum trihalide, obtaining a vaporous aluminum subhalide in one operation. 2. Способ по п.1, отличающийся тем, что получение парообразного субгалогенида алюминия ведут из пеножидкостной фазы при интенсивном перемешивании расплава в газлифтном агрегате.2. The method according to claim 1, characterized in that the production of vaporous aluminum subhalide is carried out from the foam-liquid phase with vigorous stirring of the melt in a gas lift unit.
