Abstract: A method of treating non-magnetic iron-bearing material to form an iron-rich component that is separable from a gangue-rich component is disclosed. The method comprises treating the iron-bearing material by roasting the material under reducing conditions which cause (a) formation of separate iron-rich and a gangue-rich components and (b) the iron-rich component to become magnetic. Also disclosed is a method of preparing iron-bearing feedstock for a metallurgical process. This method comprises the aforementioned treatment method and further comprises reducing the size of the treated iron-bearing material to a particle size that enables dry, magnetic separation of the iron-rich component from the gangue-rich component and magnetically separating the iron-rich component from the gangue-rich component.
