The Agbaja Iron Ore project in Kogi State Nigeria is a unique sedimentary hosted channel iron goethite deposit. The sedimentary ore allows for a simple beneficiation circuit resulting in a low-cost concentrate feed for pre-reduction and smelting to produce steel billets. However, the ore contains high levels of phosphorous (1-2 %) which need to be reduced

· Itakpe is typical of a rich ore formed by magmatic segregation whilst Agbaja is a lean ore of sedimentary origin. Isothermal mass-change measurements in hydrogen and carbon monoxide in the range 800–1100°C show Agbaja to be less reducible than Itakpe; in particular, Agbaja is very irreducible at 1100°C because of sintering of the ore.
