steel industry, manganese ore containing 28 to 35% manganese is used. Ore size generally varies from 10 to 40 mm. For manganese ore used in ferro-manganese industry, besides manganese content, other important considerations are high manganese to iron ratio and a very low content of harmful phosphorus.

manganese processing, preparation of the ore for use in various products.. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal.
