Iron is a component in all mineral classes. It occurs chiefly as reduced, ferrous iron with magnesium in silicates such as olivine, pyroxene, amphibole and biotite. It is also present in pyrite, pyrrhotite, magnetite and ilmenite. In sedimentary rocks, iron occurs generally in the oxidized, ferric state in the minerals hematite, goethite, siderite and magnetic, and in …

Goethite Goethite is a common iron mineral that is a hydrous oxide of iron, with the chemical formula α-FeOOH. It has a large specific surface area and high chemical activity, and is widely found in the earth''s crust. It is the second most common natural ore and generally contains approximately 80 to 90% Fe2O3.
