Abstract
EL TRATAMIENTO DE ACIDO SULFURICO DILUIDO CONTENIENDO SULFATO DE HIERRO II ORIGINADO EN LA PRODUCCION DE HIDROXIDO DE TITANIO SEGUN EL PROCEDIMIENTO DE SULFATADO PARA SU APLICACION EN EL PROCESO SE EFECTUA A TRAVES DE PRECONCENTRACIONES EN VARIAS ETAPAS (V1, V2, V3) DE UN 28% A UN 40 A 65% DE CONCENTRACION EN UNA EVAPORACION A VACIO, EMPLEANDO VAPOR DE AGUA ORIGINADO EN UNA ETAPA POSTERIOR Y A TRAVES DE CONCENTRACION (A) DEL 70 AL 85% CON SEPARACION DE LA SAL METALICA PRECIPITADA. SE CONCENTRA LA SOLUCION Y SE MEZCLA CON EL ACIDO (M) LIBRE DE SALES METALICAS QUE TIENE PRECONCENTRACIONES (V3) PARA OBTENER UNA MEZCLA CON UNA CONCENTRACION DE SULFURICO DEL 70%. EL RESTO DEL ACIDO NO CONCENTRADO CONDUCIDO EN EL CIRCUITO SE CONCENTRA ELEVADAMENTE ENTRE UN 85 A 88% Y SE VUELVE A EMPLEAR DE NUEVO PARA LA DISGREGACION DE MINERAL DE TITANIO. PUEDE MEZCLARSE TAMBIEN UN 85 A 88% DE ACIDO SULFURICO ELEVADAMENTE CONCENTRADO CON ACIDO SULFURICO PRECONCENTRADO.
