iron hematite magnetite and goethite. The predominant minerals in DSO are usually the ferric iron oxides hematite (Fe 2 O 3), goethite (FeO(OH) and/or limonite (FeO(OH).nH 2 O) By comparison, magnetite ore typically has a much lower iron content when mined of between 25% and 40% Fe and in this form is unsuitable for steel making.

Goethite - Wikipedia

Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethites hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is …

goethite in iron ore -

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.

Goethite: The mineral goethite information and …

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 is also frequent as black crystal sprays that form within geodes on drusy Quartz.
