Manganese is not found as a free element in nature. It is often found in combination with iron. The most important manganese ore is pyrolusite. Manganese is primarily used in iron and steel industry. It is the basic raw material for manufacturing steel alloys. 6 kilograms of manganese ore is required for manufacturing one tonne of steel.

Here, the metal is used as an alloying component. 1% of manganese turns steel into stainless steel. Manganese steel, containing up to 15% Mn, has high hardness, strength, and wear resistance. Manganese improves steel's weldability because it lowers the melting point of oxides, making the welding process easier.

Origin of Manganese Nodules. The formation of manganese nodules on the ocean-floor results from the slow precipitate of metallic minerals that are extracted directly from the sea-floor or from the pore waters in the sea- bottom sediments.
