Uses
Steel becomes harder when it is alloyed with manganese. It hassimilar applications when alloyed with aluminum and copper. Hardenedsteel is important in the manufacture of construction materials likeI-beams (24% of manganese consumption), machinery (14% of manganeseconsumption), and transportation (13% of manganese consumption).

Manganese dioxide is used to: manufacture ferroalloys; manufacturedry cell batteries (it's a depolarizer); to "decolorize"glass; to prepare some chemicals, like oxygen and chlorine; and to dryblack paints. Manganese sulfate (MnSO₄) is used as achemical intermediate and as a micronutrient in animal feeds and plantfertilizers. Manganese metal is used as a brick and ceramic colorant,in copper and aluminum alloys, and as a chemical oxidizer andcatalyst. Potassium permanganate (KMnO₄) is used as abactericide and algicide in water and wastewater treatment, and as anoxidant in organic chemical synthesis.
