About Manganese
Essential trace element for bone formation and metabolism. Used in steel production to increase strength and workability. Alkaline batteries use manganese dioxide. The name means magnet in Greek though manganese itself is not magnetic. Potassium permanganate is a powerful oxidizer used in water treatment. Manganese nodules on the ocean floor are a potential future mining resource.
