Goethite - Wikipedia
Goethite 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).
Understanding the effects of goethitic iron ore - …
Iron ore composition Compared with hematite and magnetite, goethite has a much more diverse range of textural forms and occurrences, and its influence on iron ore processing is less understood. Currently, most analysis of the effects of goethite on mine performance considers only the chemistry of the ore and not its textural components.

Haematite and magnetite are the most commonly found iron ore minerals. The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots.

IRON COUNTY: Goethite is a widespread mineral throughout the Gogebic Iron Range. It forms with hematite as a secondary alteration product of iron minerals in the iron formation and associated ferruginous schists. It often replaces primary minerals such as magnetite, ferrodolomite and siderite. It also forms concretionary and oolitic masses.
