WebDescription: Goethite is a common iron mineral. It often forms by weathering of other iron-rich minerals, thus is a common component of soils. It may form excellent pseudomorphs after the original minerals particularly pyrite or marcasite. WebThe thermal decomposition of iron ore involves the decomposition of hematite and hydrated minerals (such as goethite, kaolinite, and gibbsite). Goethite, as a mineral produced through the weathering of hematite, contains crystalline hydrate. Its thermal decomposition reaction is the process of dehydration into hematite.
