Goethite Iron Ore

Goethite: Mineral information, data and localities.

The most common simple iron oxide mineral. A weathering product of numerous iron-bearing minerals. Goethite may crystallize from a precursor - a not approved species called proto-goethite.May also form due to mineralization of lichen (Parmelia conspersa) thalli on metamorphics (e.g., gneisses), granites, feldspars.Sulfidation of goethite into mackinawite and pyrrhotite is described by Wang ...

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 ...

Goethite is found throughout the world, though collection-worthy specimens are less common. Branching stalactites and botryoidal masses, often associated with bright contrasting Vanadinite, come from the Four Man Mine, Taouz, Morocco.Recent finds of branching Goethite pseudomorphs after Marcasite are exceptional at the Farfara Oasis, in the White Desert of Egypt.
