Limonite Iron Ore - Description, chemical formula and uses

Limonite is another ore of iron, this time with a chemical formula of FeO(OH)·nH 2 O, although it can be rather variable in compositions so could have other formulas, and is not considered a true mineral because of the variability of structure and is a mixture of other minerals. A lot of what is considered Limonite is actually Geothite, an iron oxide which is the most common component of iron ...
