Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3 ), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for “blood,” in allusion to its red colour. Many of the various forms of hematite have separate
Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.
Iron is also found combined with other elements in hundreds of minerals of greatest importance as iron ore are hematite ferric oxide Fe 2 O 3 magnetite triiron tetroxide Fe 3 O 4 limonite hydrated ferric oxide hydroxide FeO OH ∙nH 2 O and siderite ferrousget price
Iron (III) oxide (α-Fe 2 O 3), commonly known as hematite, is an n-type s/c. Compared with β-Fe2 O 3 and γ-Fe 2 O 3, α-phase is the most stable and frequently occurring polymorph with a rhombohedral-hexagonal structure.
Hematite Group.The iron analogue of Corundum, Eskolaite, and Karelianite. Hematite is rather variable in its appearance it can be in reddish brown, ocherous masses, dark silvery-grey scaled masses, silvery-grey to black crystals, and dark-grey masses, to name
Hematite is a common iron oxide mineral that can be found in the form of masses, botryoidal, tabular, and the rarest form, rhombohedral. This mineral, originally referred to as “Haematite” wasn’t officially discovered until 1773 by Jean Baptiste rome de I’Isle who removed the first “e” to make it “Hematite.”

Pure hematite consists of 70% iron and 30% oxygen by weight. It might be interesting to realize that having such a high percentage of iron makes hematite a ferromagnet. But it is not true as the presence of the left small percentage of other elements, alter the magnetic properties of hematite.
