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 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are knownProperties and End-Use Functionality of Iron Ore,Properties and End-Use Functionality of Iron Ore Introduction.

Hematite: A primary ore of iron and a pigment mineral

Iron Furnace: In the 1700s and 1800s, small mines in the eastern United States produced hematite which served as the primary iron ore of the region. The ore was processed by heating it by burning charcoal in simple stone furnaces. The iron ore deposits were small and difficult to exploit.Study of Electrical Properties of Iron Ore in View of,,01.03.2014· The iron content in the original sample is 37.5 %, the basicity index 0.67 and 73.0 silicon module demonstrates this weak metallurgical properties and the need to upgrade the ore by ore- mechanical processes.
