High-grade iron is crushed for sizing, producing both fine ore as well as lump ore. To beneficiate low-grade ore, different methods can be used individually or step by step: washing, screening, magnetic separation and concentration etc (Babich et al., 2008).Nigeria is blessed with a large deposit of iron ore at Itakpe in Kogi state. The Itakpe iron ore belongs to the metamorphic ore not fully banded. The ore
