<p>A method of extraction of the metal phase from a disperse mixture consisting of at least one light metal (aluminium or its alloys, in particular) and at least one non-metal phase (oxides, oxide compounds, salts etc.) includes: (a) charging the mixture into a metallurgical vessel (2) heating it to 20-250 degrees C above the liquidus point of the metal phase; (b) homogenising the charge by rotational mixing; (c) increasing the radial acceleration up to at least 1 g, and maintenance of this acceleration for at least 0.015 hr; (d) reducing the radial acceleration to zero within a period longer than 0.03 hr; and (e) extraction of the metal and non-metal phases from the vessel. Also claimed is the apparatus.</p> |
