Abstract

The pre-oxidized ore is reduced to form metallic Fe in association with TiO2 or activated ilmenite, and lixiviated to eliminate Fe and leave a TiO2 concentrate, the oxidizing pretreatment, pref. at 900-1200 degrees C, completely converting the ore into a mixed phase ferropseudobrookite-pseudobrookite, or pseudobrookite and rutile or mixt. thereof.
