Abstract

PROCEDE ET APPAREILLAGE POUR ELIMINER LES METAUX ALCALINS OU ALCALINO-TERREUX CONTENUS EN IMPURETES DANS L'ALUMINIUM FONDU PAR REACTION AVEC DU FLUORURE D'ALUMINIUM. DANS UN RECIPIENT CYLINDRIQUE VERTICAL 10 CONTENANT L'ALUMINIUM FONDU 11, ON AGITE LE METAL FONDU DANS DES CONDITIONS CONDUISANT A LA FORMATION D'UN TOURBILLON ET DE COURANTS A COMPOSANTS DIRIGES VERS LE BAS ET SUR LES COTES AU FOND DU TOURBILLON ET A LA FORMATION DE COURANTS ASCENSIONNELS HELICOIDAUX DANS LA PERIPHERIE DU RECIPIENT, ON ENVOIE DANS LE TOURBILLON LES PARTICULES DE MATIERE CONTENANT DU FLUORURE D'ALUMINIUM, ON POURSUIT L'AGITATION JUSQU'A LA DIMINUTION VOULUE DES TENEURS EN METAUX ALCALINS ET ALCALINO-TERREUX ET ON SEPARE L'ALUMINIUM FONDU DES FLUOALUMINATES DE METAUX ALCALINS ET ALCALINO-TERREUX FORMES EN PRODUITS DE REACTION.METHOD AND APPARATUS FOR REMOVING ALKALINE OR ALKALINO-EARTH METALS CONTAINED AS IMPURITIES IN MELT ALUMINUM BY REACTION WITH ALUMINUM FLUORIDE. IN A VERTICAL CYLINDRICAL CONTAINER 10 CONTAINING THE MOLTEN ALUMINUM 11, THE MELT METAL IS STIRRATED UNDER CONDITIONS CONDUCTING TO THE FORMATION OF A VIRGIN AND CURRENTS WITH COMPONENTS DIRECTED DOWNWARDS AND SIDES AT THE BOTTOM OF THE VIRGIN AND TO THE FORMATION FROM HELICOIDAL ASCENSION CURRENTS IN THE PERIPHERY OF THE CONTAINER, THE PARTICLES OF MATERIAL CONTAINING ALUMINUM FLUORIDE ARE SENT INTO THE SWIRL, THE AGITATION IS CONTINUED UNTIL THE DESIRED DECREASE IN ALKALINE AND ALKALSE-EARTH METAL CONTENTS. 'MELTED ALUMINUM FROM FLUOALUMINATES OF ALKALINE AND ALKALINO-EARTH METALS FORMED IN REACTION PRODUCTS.
