Goethite: The mineral goethite information and pictures
Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths.
Goethite | mineral | Britannica
Goethite is the source for the pigment known as yellow ochre; it is also the primary mineral in some important iron ores, such as those in the Alsace-Lorraine basin in France. Other important goethite deposits are found in the southern Appalachians, U.S.; Brazil; South Africa; Russia; and Australia.

Goethite present in iron ore deposits affects how your mine manages the handling and processing of ore. Failing to understand how the different textural composition of goethite impacts processing performance can lead to downtime and reduced mine efficiency.
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.

Types of Iron Ore: Hematite vs. Magnetite | INN
Did you know that there are different types of iron ore? Iron is most often found in hematite and magnetite ores, though goethite, limonite and siderite ores are also common sources.
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 colour 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),...

In iron ore, goethite forms during supergene metasomatic replacement of fine-grained chert and other gangue minerals (Morris, 1985, Dukino et al., 2000) with the formation initially of ferrihydrite, FeO[OH] 3 ·nH 2 O, which is subsequently dehydrated and recrystallised to form goethite (Dukino et al., 2000).
