Electrolytic manganese is the purest form of the metal manganese, which has the chemical symbol Mn. The word "electrolytic" means that a significant portion of the processing relies on electrolysis, a reaction propelled by an electric current. More cost-effective processes produce less pure versions like silicomanganese and ferromanganese.
