READ MOREAlmost all sedimentary iron deposits contain hematite and magnetite along with other minerals. These materials are often in close association though both contain iron in different oxidation states. Magnetite holds a higher content of iron and is easier to process, but hematite is leading in iron ore production because it is more abundant.
READ MOREMagnetite. Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.
