    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)183;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.

    Dry high intensity magnetic separation (DHIMS) is investigated to process a lean hematite ore. It was found that the feed particle size and the drum rotation speed have significant influences on the separation performance, and a magnetic concentrate assaying 36.22% Fe with 75.97% recovery is achievable from the ore assaying 29.14% Fe at a coarse particle size below 10 mm.

    Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch peoples attention and they are denser than most other rocks.
