Title (EN) PROCEDURE FOR OBTAINING CALCIUM ALUMINATE FROM WASTE OBTAINED FOLLOWING TREATMENT OF SALINE DROSS FROM THE PRODUCTION OF SECONDARY ALUMINIUM
(ES) PROCEDIMIENTO PARA OBTENER ALUMINATO CÁLCICO A PARTIR DEL RESIDUO OBTENIDO TRAS EL TRATAMIENTO DE LAS ESCORIAS SALINAS PROCEDENTES DE LA PRODUCCIÓN DE ALUMINIO SECUNDARIO
(FR) PROCÉDÉ POUR OBTENIR DE L'ALUMINATE CALCIQUE À PARTIR DU RÉSIDU OBTENU APRÈS TRAITEMENT DES SCORIES SALINES ISSUES DE LA PRODUCTION D'ALUMINIUM SECONDAIRE
Abstract:
(EN) Procedure for obtaining calcium aluminate from the dry waste generated in the treatment, for recovery of metallic Al and salts, of the saline dross produced in the metallurgy of secondary aluminium and calcium oxide and/or CaO precursor. The procedure may produce briquettes or pellets of precursors of calcium aluminate through cold sintering or premolten calcium aluminate through hot sintering.
(ES) Procedimiento para obtener aluminato cálcico a partir del residuo seco generado en el tratamiento, para la recuperación del Al metálico y sales, de las escorias salinas producidas en la metalurgia del aluminio secundario y óxido de calcio y/o precursor de CaO. El procedimiento puede producir briquetas o pellets de precursores de aluminato cálcico mediante sinterizado en frío o aluminato cálcico prefundido mediante sinterizado en caliente.
(FR) L'invention concerne un procédé pour obtenir de l'aluminate calcique à partir du résidu sec généré lors du traitement, pour la récupération de l'Al métallique et de sels, des scories salines produites dans la métallurgie de l'aluminium secondaire et d'oxyde de calcium et/ou de précurseur de CaO. Le procédé permet de produire des briquettes ou des pellets de précurseurs d'aluminate calcique par sintérisation à froid ou d'aluminium calcique préfondu par sintérisation à chaud.
