What Are the Different Uses of Manganese? (with pictures)

Sep 18, 2018The ore is particularly useful in increasing steel's resistance to oxidation, so manganese is often used to make stainless steel. The addition of manganese to steel can also improve the overall strength and workability of the material. Hadfield Steel is one example of a mixture of steel and manganese, and is known for both these properties.

In 1774, Manganese was first isolated when the mineral pyrolusite, MnO 2, was fired in a charcoal container.When the oven cooled, a small amount of greyish manganese was produced. Manganese ore was first confused with magnetic iron ore. The most common oxide and mineral is pyrolusite.Mines in the Soviet Union, India, and South Africa produce ores containing as much as 40% manganese.
