Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA DESCOMPOSICION DE UN LIQUIDO DE ALUMINATO DE SODIO SOBRESATURADO DE ALUMINA. CONSISTE EN DESENCADENAR LA DESCOMPOSICION DEL LIQUIDO DE ALUMINATO DE SODIO SOBRESATURADO DE ALUMINA, PROCEDENTE DEL ATAQUE ALCALINO DE BAUXITA SEGUN EL PROCEDIMIENTO BAYER, MEDIANTE LA INTRODUCCION EN DICHO LIQUIDO DE UN CEBO DE TRIHIDRATO DE ALUMINA, FORMANDO ASI UNA SUSPENSION, LA CUAL ES INTRODUCIDA EN LA PARTE SUPERIOR DE UN REACTOR DENOMINADO <<DESCOMPONEDOR>>, Y TOMADA EN LA PARTE INFERIOR DE DICHO DESCOMPONEDOR. LA VELOCIDAD DE CIRCULACION DE LA SUSPENSION HA DE ESTAR COMPRENDIDA ENTRE 1,5 Y 10 METROS POR HORA.
