Abstract
Procedimiento para la preparación de ácido sulfúrico a partir del ácido sulfúrico residual que contiene sulfato de hierro, que resulta al disgregar con ácido sulfúrico materiales que contienen TiO2, en el que sulfato de hierro rico en agua de cristalización se transforma en sulfato de hierro pobre en agua de cristalización por elevación de la concentración de ácido sulfúrico, y se separa por filtración como material sólido, la concentración de ácido sulfúrico del producto filtrado acuosos se aumenta por evaporación de agua, una corriente parcial del producto filtrado concentrado se añade al ácido sulfúrico residual, y se obtiene ácido sulfúrico a partir del sulfato de hierro pobre en agua de cristalización, sólido, separado por filtración.
