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(III) oxide-hydroxide - Wikipedia
Iron oxide-hydroxide or ferric oxyhydroxide is the stone compound of iron, oxygen, and hydrogen with formula FeO. The compound is often encountered as one of its hydrates, FeO(OH)·nH 2O. The monohydrate FeO(OH)·H 2O is often referred as iron hydroxide Fe 3, hydrated iron oxide, yellow iron oxide, or Pigment Yellow 42.

Iron ore hydroxide - homeofhope4allnl. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe) It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4 ) and hematite (Fe 2 O 3 ) Iron ore is the source of primary iron for the worlds iron and steel industri It is therefore essential for .
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.

Goethite - Wikipedia
Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethites 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 iron ore") but is more typically massive.
