    Hematite. Mineral Description. Hematite is an iron oxide mineral of the Oxides and Hydroxides group, with structural formula [alpha Fe2O3]. The structure is similar to that of corundum, and consists essentially of a dense arrangement of Fe3+ ions in octahedral coordination with oxygen atoms in hexagonal closest packing.

  • Hematite Wikipedia

    Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. It is the oldest known iron oxide mineral and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and.
