Detailed Solution

Manganese is mainly used in the manufacturing of steel and ferromanganese alloys.
Ten kilograms of manganese are required to make one tonne of steel. Manganese makes up roughly 0.1% of the Earth's crust and is the 12th most common element in the universe. It got employed in chemical processes such as oxidants and pigments. Manganese's significance to human societies increased dramatically with the development of modern steelmaking techniques in the 1860s. Only a few countries control the world's manganese mining, a mineral that is essential and irreplaceable in steel manufacture. Odisha is India's top state for manganese ore production. It was responsible for one-third of the nation's total iron ore production in 2000–2001.
