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 (/ˈɡɜːrtaɪt , US also /ˈɡoʊθaɪt ) is a mineral of the diaspore group, consisting of iron(III) oxide-hydroxide, specifically the α polymorph. It is found in soil and other low-temperature environments such as sediment. Goethite has been well known since ancient times for its use as a pigment (brown ochre).

Deposits with less than 30 percent iron are commercially unattractive, and, although some ores contain as much as 66 percent iron, there are many in the 50–60 percent range. An ore’s quality is also influenced by its other constituents, which are collectively known as gangue.
