Pyrolusite (MnO 2) is the major ore. Manganese ores are produced principally in South Africa, Australia, China, Brazil, Gabon, Ukraine, India, and a few other countries. The metal is prepared commercially by reduction of its ores with aluminum or, with high purity, by electrolysis of a manganese sulfate solution.
Manganese dioxide. It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols. MnO 2 in the α polymorph can incorporate a variety of atoms (as well as water molecules) in the "tunnels" or "channels" between the manganese oxide octahedra. There is considerable interest in α-MnO 2 as a possible cathode for lithium ion batteries.

Secondly, the soluble MnO from the reduced low grade MnO2 ore was leached by dilute sulphuric acid to be MnSO4 solution at 80 °Cin 30min, and lastly the honeycomb-like structure MnO2 can be prepared by the redox reaction of mixed MnSO4 and KMnO4 solution.
The Crimora Mine, located in Augusta County, was the largest producer of manganese in the United States. The Crimora Mine operated as early as 1867, and continued off and on until 1959. The U.S. government purchased and stockpiled manganese ore produced from Augusta County during the 1950s at Riverville, Amherst County.
Manganese is a silvery-gray metal and is part of the group known as the transition metals.It is similar to iron. It is hard to melt, but easy to oxidize.Manganese forms chemical compounds in several oxidation states: +2, +4, and +7 are the most common.Manganese compounds can be black, brown, pink, red, green, blue, and purple.
