Overview. Results of beneficiation of hematite. Hematite is a kind of iron oxide ore, the main component is Fe2O3, it is dark red, the specific gravity is about 5.26, and it contains 70% Fe and 30% O. It is the most important iron ore. Primary hematite contains impurities, and its grade is difficult to reach the best standard for smelting.
