The iron analogue of Corundum, Eskolaite, and Karelianite. Hematite is rather variable in its appearance it can be in reddish brown, ocherous masses, dark silverygrey scaled masses, silverygrey to black crystals, and darkgrey masses, to name a few. What they all have in common is a rustred streak. Black crystals may be confused with ilmenite.
Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances.
