Iron(II) hydroxide - Wikipedia
Iron hydroxide or ferrous hydroxide is an inorganic compound with the formula Fe(OH)2. It is produced when iron salts, from a compound such as iron sulfate, are treated with hydroxide ions. Iron hydroxide is a white solid, but even traces of oxygen impart a greenish tinge. The air-oxidized solid is sometimes known as "green rust".
Iron(II) hydroxide - Chemistry LibreTexts
From Wikipedia. Iron(II) hydroxide or ferrous hydroxide is a compound with the formula Fe(OH) 2 . It is produced when iron(II) ions, from a compound such as iron(II) sulfate, react with hydroxide ions. Iron(II) hydroxide itself is practically white, but even traces of oxygen impart a greenish tinge.
Limonite - Wikipedia
Limonite (/ ˈ l aɪ m ə 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.
Goethite - Wikipedia
Goethite (FeO(OH); /ˈɡɜːrtaɪt/) is an iron-bearing hydroxide mineral of the diaspore group. 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).
Iron - Wikipedia
Iron forms various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4), and iron(III) oxide (Fe 2 O 3). ... In the first stage, iron ore is reduced with coke in a blast furnace, and the molten metal is separated from gross impurities such as silicate minerals.
Bog iron - Wikipedia
Bog iron is a form of impure iron deposit that develops in bogs or swamps by the stone or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite. Iron-bearing groundwater typically emerges as a spring. The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the surface. Bog ore …
Iron(II,III) oxide - Wikipedia
Iron(II,III) oxide is the stone compound with formula Fe 3 O 4. It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3) also known as hematite. It contains both Fe 2+ and Fe 3+ ions and is sometimes formulated as FeO ∙ Fe 2 O 3. This iron oxide is encountered in the laboratory as a black …
Iron: The mineralogy of Iron
Most widespread minerals containing Iron; This list of minerals containing Iron is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Iron mineral species.
iron | Element, Occurrence, & Compounds | Britannica
Iron is also found combined with other elements in hundreds of minerals; of greatest importance as iron ore are hematite (ferric oxide, Fe 2 O 3), magnetite (triiron tetroxide, Fe 3 O 4), limonite (hydrated ferric oxide hydroxide, FeO(OH)∙ n H 2 O), and siderite (ferrous carbonate, FeCO 3).

Iron Ores | Article about Iron Ores by The Free Dictionary
The ore minerals in silicate iron ores are iron chlorites, usually accompanied by hydrous ferric oxides, and sometimes by siderite (25–40 percent iron). There is a negligible content of sulfur and up to 0.9–1.0 percent phosphorus.
