natural occurrence of iron ore

  • 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). Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which Iron Ore Statistics and Information U.S. Geological Survey6 天之前  Nickel-iron, a native alloy, occurs in terrestrial deposits (21–64 percent iron, 77–34 percent nickel) and in meteorites as taenite (62–75 percent iron, 37–24 percent nickel).

    The principal ores of iron are hematite (ferric oxide, Fe 2 O 3) and limonite (ferric oxide trihydrate, Fe 2 O 3 3H 2 O). Other ores include siderite (ferrous carbonate, FeCO 3 ), The most important iron-containing minerals are the oxides and sulfides. Hematite (red iron ore, Fe 2 O 3), magnetite (loadstone, Fe 3 O 4), and goethite (hydrous iron oxide, FeO 2 The Distribution of Iron in Nature SpringerLinkIron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by Iron processing - Ores, Smelting, Refining Britannica
