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 steel and aluminum.

The advantages of the Mesa sulfur dioxide leach process relative to a conventional manganese oxide ore roasting process include:

• An improvement in metal purity from the more common 99.5% or 99.7% standards to the less common 99.8% standard making the output of the plant more attractive to industries requiring high purity (eg, in the electronics industry where EMM is used as feedstock for the production of ferrites);
• A very significant reduction in ore acquististion costs;
• A 50% reduction in energy consumed;
• The total elimination of carbon dioxide emissions;
• The creation of a second fertilizer product from the plant tailings (ie, a cost of production transformed into a valuable revenue);
• The ability to eliminate virtually all particulate and metal ion emissions; and
• The elimination of hydrogen sulfide gas from the cell house improving occupational health and safety conditions.

Features

Electrolytic metal manganese has a high purity of 99.9% without using selenium (Se), a harmful heavy metal, during the manufacturing process. While the product is normally provided in flakes, we can also provide it in powder form.

Uses

Manganese additives for non-ferrous metals, manganese raw materials for special steels, raw materials for industrial chemicals, among others.
