What Is Electrolytic Manganese? - wiseGEEK

2021-2-21  Electrolytic manganese is a pure form of the metallic element manganese, Mn. It is termed "electrolytic" because a major step in the refining process involves electrolysis, a chemical reaction driven by an electric current. Less pure forms, such as ferromanganese and silicomanganese, are derived by more economical methods. The pure metal is primarily used as an alloy in the production of stainless
