Abstract High-purity ilmenite, FeTiO 3, was prepared by the sol–gel method and calcination under nitrogen atmosphere. Several FeTiO 3/TiO 2 catalysts were pre-pared by the impregnation method using ilmenite and titania, both synthesized by the sol–gel method with ethanol and acetic acid. FeTiO 3/TiO 2 photocatalysts ex-
The reduced ilmenite is then batch-digested in rot ary-ball digesters with 18-20% HCl at 140° C. Ferrous oxide in the ilmenite is converted to soluble ferrous chloride, and the TiO 2 portion of the ilmenite is left as a solid. Spent acid liquor, which contains excess HCl and ferrous chloride, is sent to an acid regeneration circuit. The TiO 2
