Manganese is essential to iron and steel production by virtue of its sulfurfixing, deoxidizing, and alloying properties.
Pyrolusite is an oxidation product of weathered manganese minerals and also forms from stagnant shallow marine and freshwater bog and swamp deposits. Minerals such as rhodochrosite, rhodonite and hausmannite are often replaced by pyrolusite.
Manganese improves the strength properties of steel, while marginally impairing its elasticity. In addition, manganese has favourable influence on forging, welding and grain refining properties

Manganese metal is graywhite, resembling iron, but is harder and very brittle. The metal is reactive chemically, and decomposes cold water slowly. Manganese is widely distributed throughout the animal kingdom. It is an important trace element and may be essential for utilisation of vitamin B. Manganese is present in quantity the floor of oceans.
