ABSTRACT:
Beneficiation of ilmenite using a process comprising first reducing by a known process the iron component thereof to metallic iron to form particles containing a mixture of iron and titanium oxide and then treating these particles with an iron salt or a precursor thereof, at an elevated temperature, to segregate the iron from the titanium-bearing component. The segregated iron is separated from the titanium bearing component by physical or chemical means.
