    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.

    Abstract: A process for lowering the concentration of phosphorus in iron ore is disclosed. The process comprises roasting and then leaching iron ore or upgraded concentrates of iron ore having a concentration of at least 0.05 wt. % phosphorus to lower the phosphorus level in the iron ore and then washing leached iron ore to at least partially remove leach liquor retained on the iron ore. The process allows more extensive exploitation of high phosphorus resources than is currently possible.
