  • Goethite Morphology and Composition in Banded Iron

    Goethite Morphology and Composition in Banded Iron

    ing. Goethite is reported to occur as a ubiquitous phase in many iron ore types and is particularly abundant in the Precambrian banded iron ore formation of north Orissa, India. Goethite from the Bonai – Keonjhar Belt in Orissa has been examined in terms of its morphology and microstructure in relation to chemical composition.

    Goethite Mineral Physical Optical Properties Uses

    Apr 27, 2018 Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. Goethite may occur with these minerals in the gossan, or iron hat, which is the weathered capping of an iron ore deposit.
