  2. Iron oxide - Wikipedia

    en.wikipedia.org/wiki/Iron_oxide

    Iron oxides feature as ferrous or ferric or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. Oxides of Fe II. FeO: iron(II) oxide, wüstite; Mixed oxides of Fe II and Fe III. Fe 3 O 4: Iron(II,III) oxide, magnetite; Fe 4 O ...

  3. Iron (III) oxide-hydroxide - Wikipedia

    en.wikipedia.org/wiki/Iron(III)_oxide-hydroxide

    Iron(III) oxide-hydroxide or ferric oxyhydroxide [2] is the chemical compound of iron, oxygen, and hydrogen with formula FeO(OH). The compound is often encountered as one of its hydrates, FeO(OH) ·n H 2 O [rust]. The monohydrate FeO(OH) · H 2 O is often referred to as iron(III) hydroxide Fe(OH) 3, [3] hydrated iron oxide, yellow iron oxide ...

  4. Goethite - Wikipedia

    en.wikipedia.org/wiki/Goethite

    Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle ironstone" [3]) but is more typically massive. [2]

  5. Iron-oxidizing bacteria - Wikipedia

    en.wikipedia.org/wiki/Iron-oxidizing_bacteria

    The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...

  6. Iron sucrose - Wikipedia

    en.wikipedia.org/wiki/Iron_sucrose

    The iron sucrose molecule is a polymer with two main molecules; sucrose (chemical formula C 12 H 22 O 11) and an iron (III) hydroxide (Na 2 Fe 5 O 8 •3(H 2 O)). These two components are in solution together, but are not bound to one another. [2] Iron sucrose is a type II complex, with two oxygen atoms bonded to each iron atom. [3]

  8. Bog iron - Wikipedia

    en.wikipedia.org/wiki/Bog_iron

    Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides , commonly goethite (FeO(OH)).

  9. Ferrihydrite - Wikipedia

    en.wikipedia.org/wiki/Ferrihydrite

    Ferrihydrite (Fh) is a widespread hydrous ferric oxyhydroxide mineral at the Earth's surface, [6] [7] and a likely constituent in extraterrestrial materials. [8] It forms in several types of environments, from freshwater to marine systems, aquifers to hydrothermal hot springs and scales, soils , and areas affected by mining.
