Abstract

UN METODO DE ELIMINAR METALES ALCALINOS Y METALES ALCALINO-TERREOS CONTAMINANTES DE ALUMINIO FUNDIDO.SE EFECTUAN LAS SIEGUIENTES OPERACIONES: 1.O) COLOCAR UNA CARGA DE ALUMINIO METALICO CONTAMINADO EN EL INTERIOR DE UN RECIPIENTE VERTICAL; 2.O) AGITAR EL ALUMINIO FUNDIDO 3.O) SUMINISTRAR UN MATERIAL A BASE DE FLUORURO DE ALUMINIO CONSTITUIDO POR PARTICULAS 4.O) CONTINUAR LA AGITACION DEL ALUMINIO FUNDIDO HASTA QUE EL CONTENIDO DE METALES ALCALINOS Y ALCALINOTERREOS SE REDUCE A UN NIVEL BAJO DESEADO 5.O) SEPARAR EL ALUMINIO FUNDIDO DE LOS PRODUCTOS DE REACCIONDE FLUOALUMINATOS FUNDIDOS. LA AGITACION SE ESTABLECE DE FORMA QUE SE FORME UN TORBELLINO EXCENTRICO EN RELACION AL EJE DEL RECIPIENTE. EL METAL FUNDIDO SE TRATA CON ALF3 O NAF. ALF3 EN POLVO CON UNA BAJA RELACION EN PESO DE NAF/ALF3.
