    OverviewNamesCharacteristicsFormationUses of limoniteHistorySee alsoExternal links

    Limonite is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and has been mined for the production of iron since at least 2500 BCE.

    Limonite is the catchall name widely applied to hydrous iron oxide minerals. Goethite [α-Fe 3+ O (OH)], which is hexagonal, is the most common of these minerals; indeed, in nature most FeO (OH) minerals ultimately become this α-phase. Goethite, much of which has the general colour of iron iron processing: Ores.

    CharacteristicsFormationUses of LimoniteHistoryLimonite is relatively dense with a specific gravity varying from 2.7 to 4.3. It varies in colour from a bright lemony yellow to a drab greyish brown. The streak of limonite on an unglazed porcelain plate is always brownish, a character which distinguishes it from hematite with a red streak, or from magnetite with a black streak. The hardness is variable, but generally in the 4 5.5 range.Although originally defined as a single mineral, limonite is now recognized as a mixture of related hydr...
