Manganese - Wikipedia

Manganese is a chemical element with symbol Mn and atomic number 25 It is not found as a free element in nature; it is often found in minerals in combination with iron Manganese is a metal with important industrial metal alloy uses, particularly in stainless steelsManganese: Nodules, Uses, Facts, Ore, Alloys, Metal,Manganese ores are widespread, but most of the world’s supply is from a small number of manganese mining districts Most manganese ores are from extensive layers of manganese-rich sedimentary rocks that formed in ancient oceans under specialized conditionsThe Properties and Effects of Manganese as an Alloying Element,Manganese, as a desulfurizer, forms stable, high-melting sulfide particles, and manganese as an alloying agent enhances hardness, strength, abrasion resistance, and hardenability After briquetting with aluminum shot, powdered electrolytic manganese is mixed with aluminum in up to 2% concentration
