Manganese Ore

Manganese Ore (Mn) is an important and indespensible input raw material for steel making

Mn ore’s consumption is among the key indicators of industrial development in any country.

It is in the form of ferro and silicomanganese alloys are the most essential ingredients in the production of steel, both crude and stainless.

Mn ores containing iron oxides are first reduced in blast furnaces or electric furnaces with carbon to yield ferromanganese, which in turn is used in steelmaking. Adding manganese, which has a greater affinity for sulfur than does iron, converts the low-melting iron sulfide in steel to high-melting manganese sulfide. Produced without manganese, steel breaks up when hot-rolled or forged. Steels generally contain less than 1 percent manganese.

Manganese steel is used for very rugged service; containing 11–14 percent manganese, it provides a hard, wear-resistant, and self-renewing surface over a tough unbreakable core. Pure manganese produced electrolytically is used mostly in the preparation of nonferrous alloys of copper, aluminum, magnesium, and nickel and in the production of high-purity chemicals.
