agbaja iron ore beneficiation

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 be …

characterization studies on agbaja iron ore a high

Feb 02, 2019· Agbaja iron ore, ahigh-phosphorusiron ore, has been characterized using a variety of analysis techniques in an attempt to unravel the presentation and distribution of phosphorus in the iron ore (between the iron-rich phase and the gangue mineral(s) which will be very useful in planning effective beneficiation andphosphorusremoval strategies)

sintering characteristics of itakpe and agbaja iron ore

Agbaja iron ore concentrate of high phosphorus (P2O5 = 1.50 – 2.14%) and low silica content and Itakpeiron oreconcentrate of low phosphorus (P = 0.03%) and high silica in order to produce fluxed sinters suitable forpig ironproduction. The ores (Agbaja and Itakpe) were concentrated using conventional beneficiation techniques and then blended

effect of temperature on magnetizing reduction ofagbaja

Abstract Agbaja oolitic iron ore, which has not been responsive to such beneficiation processes as froth flotation, gravity concentration, magnetic separation, and electrostatic separation, has been concentrated to 60 pct Fe grade and 87.3 pet Fe recovery (starting from a crude assaying 45.6 pct Fe) by the magnetizing reduction technique

The Agbaja Project is located on the Agbaja Plateau in Kogi State, Nigeria, approximately 200 kilometres from the capital city, Abuja. The Plateau hosts an extensive, shallow, flat-lying channel iron deposit (CID) and Kogi Iron has determined a Probable Ore Reserve of 205 million tonnes at a grade of 45.7% iron (Fe), estimated in accordance with the JORC (2012) code
