Manganese ore Article about Manganese ore by The Free

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.
