Iron ore - Wikipedia

Iron ores[1] are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe ...

When phosphorus is found in solid solution in the goethite phase, the heat treatment process of the iron ore particles can be an efficient technique to its removal 7. Such treatment enables the structural rearrangement of goethite, which is converted into hematite and facilitates the release of the phosphorus to the acid leaching process.
