, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide Fe 2 O 3, that constitutes the most important ore because of its high 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 have separate names. The steel-gray crystals and coarse ...read more

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe2O3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2O 3. It has the same crystal structure as corundum Al 2O 3 and ilmenite FeTiO 3, with which it forms a complete solid solution at temperatures above 950 °C 1,740 °F. Hematite is colored black to steel or silver-gray, brown to reddish-brown, or red. It is mined as an importantread more

Extraction of Metals. Extraction of Iron. Iron is extracted from its ore in the blast furnace. The main iron ore is called haematite. Haematite is ironIII oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica silicon dioxide. Limestone calcium carbonate is added to the iron ore which reacts with the silica to form molten calcium silicateread more
