Limonite - Wikipedia

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 BC. Limonite: an iron oxide used as pigment and iron ore,The limonite streak on an unglazed porcelain plate is usually brownish, which differentiates it from the mineral hematite, with a red streak, or magnetite, with a black streak. Limonite attains magnetic properties when heated, and has an opaque appearance. The hardness of limonite varies from 4 to 5.5. References. Limonite – Minerals.netHematite (The Bloodstone Ore) - Mineral Properties and,,Dec 29, 2018· Hematite forms a solid solution series with ilmenite (known as titanohematite, hematite-ilmenite or HISS) at high temperatures. Associated Minerals. A discussion of hematite would not be complete without mentioning its frequent companions, limonite (rock composed of various iron oxides and hydro-oxides) and goethite (α-FeOOH).
