DESCRIPTION
Electrolytic manganese metal is the elemental metal extracted from manganese ore by acid leaching and then sent to electrolytic cell. The appearance looks like iron, is irregular flake, the quality is firm and brittle, one side is bright, the other side is rough, for silver white to brown, after processing for powder is silver gray; It is easy to oxidize in air and dissolves and displaces hydrogen when encountering dilute acid. At slightly higher than room temperature, it can decompose water and release hydrogen.
The main refining methods of metal manganese are thermal method (fire method) and electrolysis method (wet method). The purity of thermal production (metal manganese) is not more than 95 ~ 98%, and the pure metal manganese is prepared by electrolytic method (electrolytic metal manganese), its purity can reach 99.7 ~ 99.9%. At present, electrolysis has become the main way of manganese production.
