Overcoming the phosphorous issue at the Agbaja iron

2021-8-24  The Agbaja Iron Ore project in Kogi State Nigeria is a unique sedimentary hosted channel iron geothite 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 (1.0 – 2.0%) which ...

2020-7-15  The Iron ore is typically classified as high grade (+65% Fe), Medium grade (+62 – 65% Fe) and low grade (-62% Fe). Typically, the Integrated Steel Plants(ISPs) use medium/high-grade iron ore whereas the sponge iron plants require only high-grade iron ore, preferably, with +67% Fe. The Agbaja iron ore is traded in lumps (i.e. sized ore) or

Selective oil agglomeration of Agbaja iron ore - Mining ...

Starting from a crude ore assaying 45.6% Fe, a fine-grained oolitic iron ore was concentrated by the oil agglomeration technique to 90% Fe recovery and 65% Fe assay. The ore required grinding to minus 5 μm to effect adequate liberation, and the technique yielded optimum results at pH 9. The roles of pH, collector, and bridging liquid concentrations on selectivity and yield of iron minerals in ...

Upgrading Nigerian iron ores SpringerLink

A number of Nigerian iron ore deposits have been upgraded to the specifications of concentrates for the blast furnace and the direct reduction iron- and steel-making plants. Depending on the mineralogy of the ore deposits, the techniques of oil agglomeration, magnetizing reduction, washing and scrubbing, gravity concentration, and reverse froth flotation have been utilized. A mode of ...
