· · Fire manganese is massive and difficult to crush. Wet electrolytic manganese is flake, easily crushed and with high purity. At the same time, manganese powder production scale is generally larger with lower added value. These factors determine that the mechanical crushing method is suitable for production of manganese powder and the materials is electrolytic manganese metal.
