University of Minnesota’s Mineral Pages: Hematite

Regardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite. In Early Proterozoic (2.5 to 1.6 billion year ago) iron ore deposits, layers of hematite and other iron oxides alternate with bands of chert (microcrystalline quartz) to form distinctively layered deposits known as,Magnetite - University of Minnesota,Economic magnetite deposits primarily occur in layered igneous rocks that formed from the slow cooling of magma, heavy mineral sedimentary deposits, and Early Proterozoic (2.5 to 1.6 billion years ago) marine precipitates. The iron from magnetite and hematite deposits is the source of the steel used almost universally through our modern society,Specularite: Mineral information, data and localities.,A variety of hematite characterized by aggregates of silvery, metallic, specular ('mirror-like') hematite flakes or tabular, anhedral crystals.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, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO,Karara Mining,Karara Mining.
