Manganese: uses (1) Metallurgical applications; Steel making; At present steel making accounts for 85% to 90% of total manganese consumption. Manganese is often used by the steel industry in deoxidizing and desulfurizing additives and as an alloying constituent. It can improve the rolling and forging qualities, as well as the strength, toughness, stiffness, hardness, wear resistance, and ...

Manganese - Gordon England

An additive composition for use in steel making, which comprises 84.8-99.3 % by weight of an oxide component; 0.5-1.6 % by weight of a metal component; and 0.04-0.07 % by weight of a rare-earth element component, is used in such a way that its four aliquots are each added in blast furnace. The amount of the composition to be added is dependent on the steel to be produced.

Later, during Ancient Egyptian and Roman eras, manganese compounds added color to glass. Chemical studies of manganese during the 16th through 19th centuries led to the realization that the addition of manganese to iron ore-based steel made it even harder. In today's world, manganese is often used for cathodic shielding in the battery industry.

Manganese Mining and Processing: Everything you Need to Know

"Pure manganese oxide can be used in the steel industry as an additive in the steel manufacturing process," explains Salminen. "Solutions containing manganese and zinc are also commonly used as a fertilizer, if the concentration of impurities are low enough to qualify for agricultural use.
