Manganese (Mn) is a gray, hard, brittle, glossy metal. Manganese and other elements generate a variety of compounds, often in the form of ore in nature. The main minerals are pyrolusite (MnO_2), rhodochrosite (MnCO_3), brown manganese ore (MnO_3), manganese ore (Mn_3O_4) and so on. More than 60 kinds of manganese compounds. Common manganese compounds are manganese dioxide (MnO 2), manganese chloride (MnCl 2), manganese sulfate
