What Is Manganese

Manganese (Manganese), a chemical element, element symbol Mn, atomic number 25, is a gray-white, hard, brittle, and shiny transition metal. Pure metal manganese is a metal slightly softer than iron, and manganese with a small amount of impurities is hard and brittle, and will oxidize in wet places. Manganese is widely found in nature. The soil contains 0.25% of manganese. Tea, wheat and hard-shelled fruits contain more manganese. Operations that come into contact with manganese include gravel, mining, electric welding, production of dry batteries, and dye industries.

In 1774, Gunn isolated the metal manganese. Bergman named it manganese (manganese). Manganese can be obtained by aluminothermic reduction of pyrolusite.
