Abstract

PROCEDIMIENTO PARA LA OBTENCION DE OXIDO DE TITANIO A PARTIR DE LOS RESIDUOS DE LA DISGREGACION DE MATERIALES QUE CONTIENE TITANIO. CONSISTE EN DISGREGAR EN LA PROPORCION DE 30-75 POR 100 DE UN RESIDUO DE DISGREGACION CONTENIDO DE TIO2 MAYOR DE 80 POR 100 Y UN CONTENIDO EN TI(III) ENTRE 20-35 POR 100. LA DISGREGACION SE HACE EN ACIDO SULFURICO CON UN CONTENIDO EN H2SO4 SUPERIOR AL 86 POR 100, INICIANDOSE LA MISMA MEDIANTE ADICION DE AGUA, VAPOR DE AGUA O ACIDO SULFURICO DILUIDO. UNA VARIANTE DE ESTE PROCEDIMIENTO SUSTITUYE EL ACIDO SULFURICO POR OLEUM CON UN CONTENIDO EN SO3 DE HASTA UN 30 POR 100.
