Magnetite. Karara comprises a largescale, longlife magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (3436% Fe) than hematite ore (5864% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a highgrade (+65% Fe) concentrate for steelmaking.
In beneficiation of BHQ iron ore, the several ore dressing operations were carried out under Pilot plant, such as Size reduction (ore crushing grinding), Characterization (Size analysis, heavy media separation, microscopic studies, XRD, XRF MLA), screening, classifying (spiral classifying and hydrocyclone), Magnetic separation (Low High ...
Most of iron ore resources are composed of metamorphosed banded iron formations (BIF) in which iron is commonly found in the form of oxides, hydroxides and to a lesser extent carbonates. The chemical composition of iron ores has an apparent wide range in chemical composition especially for Fe content and associated gangue minerals.
