Direct Reduced Iron Industry in India — Problems and
2012-12-18 · Iron Ore Iron ore of the right quality is the basic input. The sponge iron plants are basically using lump ore. The chief quality requirements are: i. High Fe content with less gangue and deleterious elements like phosphorous and sulphur — preferably 65% or higher iron content. ii.
Overcoming the phosphorous issue at the Agbaja iron ore ...
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 for the crude steel to
