Limonite (/ ˈ l aɪ. m ə ˌ n aɪ t /) 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)· n H 2 O, 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 ...
Limonite used to be considered a mineral, but today the name is a field term for amorphous iron oxides that have been used as yellow to brown ocher pigments and an impure ore of iron.

Extraction of limonite ore using dissolved SO2–air is an alternative hydrometallurgical method for nickel recovery. This process is carried out at atmospheric pressure and is shown to have good selectivity of nickel over iron, but with a low recovery yield. The literature refers to the application of alkali roasting as pretreatment in laterite ore leaching to increase nickel recovery.
Limonite is a sedimentary mineral, and commonly colors soils and rocks. As a result it is often finely disseminated, mixed with clays and other minerals, or found in massive, amorphous lumps. This specimen is amorphous and earthy. The next two samples are more compact.
