Manganese

Metallurgy: (Mn) as ore concentrates andor ferro manganese & silico manganese derived from the ores is ubiquitous in the production of cast iron & steel. Iron ore, coke, and limestone are the basic feed materials used to manufacture pig iron – as coke burns it acts as the fuel to heat the blast furnace and at the same time gives off carbon monoxide which combines with the iron oxides in the ore reducing them to pig iron:
