The most important manganese ore is pyrolusite (MnO2). Other economically important manganese ores usually show a close spatial relation to the iron ores. The most important manganese ores are the oxides pyrolusite, romanechite, manganite, and hausmannite and the carbonate ore rhodochrosite. The feminine magnes ore did not attract iron, but was used to decolorize glass. This feminine magnes was later called magnesia, known now in modern times as pyrolusite or manganese dioxide. Neither this mineral nor elemental manganese is magnetic. Manganese is too brittle to be of much use as a pure metal. It is mainly used in alloys, such as steel. Steel contains about 1% manganese, to increase the strength and also improve workability and resistance to wear. Manganese is not found as the free metal in nature, however manganese minerals consisting of oxides, silicates, and carbonates are the common. Most Manganese is obtained from ores in Australia, Brazil, Gabon, India, Russia, and South Africa. Manganese nodules on ocean floors holds contain about 24% manganese. Manganese Ore is the 427th most traded product and the 1214th most complex product according to the Product Complexity Index (PCI).
