In summary, Muko ore is a high-grade hematite ore with Fe content above 65%. It has low gangue content which is within the acceptable commercial level (<6% SiO 2 and ≤4% Al 2 O 3) and low content of deleterious elements (<0.07% P and <0.1% S). It can thus serve well as a raw material for iron production.
