Ilmenite ore is roasted at temperatures in the range of 800 C to 1,000 C to selectively magnetise the ilmenite fraction so that gangue minerals may be easily removed. Roasting also enhances the subsequent leaching operation by activation of the iron component of the ilmenite whilst at the same time rendering the titania fraction insoluble.
