Iron ore Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red The iron is usually found in the form of magnetite (Fe 3 O 4, 724% Fe), hematite (Fe 2 O 3, 699% Fe), goethite (FeO(OH), 629% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCOHematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3)With this it forms a complete solid solution at temperatures aboveHematite WikipediaMajority of the iron ore deposits (Fig 51) are confined to Banded iron formation (BIF) of Proterozoic volcanosedimentary sequence (supracrustal) of age 2524Ga, 22 206Ga and 20Ga Thus, Complex genetic process has a control over the mineralogical and geochemical attribute of the iron ore, associated rocks and their host rocks The associated rocks contribute to the gangue componentCHAPTER5 GEOCHEMISTRY OF IRON ORES
