Advantages of Manganese
When it is used as an additive in other base metals such as steel, iron, and super alloys, manganese provides a wealth of benefits that include adding a stiffness and hardness to these metals. With these mechanical and structural characteristics, the popularity of manganese is increasing as its application use is spreading.

Chemical Properties of Manganese
Manganese’s key chemical properties are its reactivity, valency, electronegativity, solubility, and complex formulation. With oxygen, manganese reacts to make manganese dioxide (MnO2), manganese trioxide (Mn2O3), manganese heptoxide (Mn2O7), and other oxides. In terms of valency, manganese can have charges of anywhere from -3 to +7 (the most common being +2, +3, +4, and +7).
Manganese has quite a high electronegativity, attracting electrons towards itself in chemical reactions. Depending on their specific properties, its compounds can be soluble or insoluble. For instance, manganese sulfate is highly soluble while the opposite can be said of manganese dioxide.
Application of Manganese
Steel
Manganese is famed for its use in steelmaking (the largest global industrial use of the metal—an estimated 90%—is in this sector), so it’s only right that we start here. Used as an alloying element, adding manganese to steel not only improves the latter’s strength, hardness, wear-, and corrosion-resistance, but makes it less brittle, too.
Batteries
Manganese is commonly used to make batteries, especially alkaline, zinc-carbon, and lithium-ion ones. Manganese dioxide is typically used in alkaline battery cathodes, while in zinc-carbon batteries it’s used as a depolarizer.
Resistors
Certain types of resistors (electrical components designed to limit the current flow in a circuit) are made using manganese. By mixing manganese dioxide with carbon, the resistance factor can be ramped up anywhere from a few ohms to many megaohms.
Aluminum Alloys
After steelmaking, perhaps the next most common use of manganese is in aluminum alloys. Aluminum with manganese makes for a strong, tough, and corrosion-resistant material, which is why it’s most often used in the automotive sector for things like engine blocks, transmission components, and other parts that need to be extra strong and durable.
There are three main manganese production processes—hydrometallurgical, electrolytic, and smelting. Hydrometallurgical processes use chemical reactions to extract manganese–one of these is leaching. This method uses an acid or alkali to dissolve the manganese from the source, which is then treated to extract the manganese.
Electrolytic processes involve passing an electric current through a liquid that has manganese ions in it. The manganese then collects on the electrodes as a metal with a high purity level. Smelting processes give us manganese alloys like ferromanganese and silicomanganese. With smelting, manganese oxides are heated in a furnace with other materials like carbon or aluminum.
Safety Information of Manganese
You should take precautions to prevent inhalation of manganese by wearing an appropriate mask to limit the amount of manganese you breathe. Workers exposed to high levels of airborne manganese in certain occupational settings may accumulate manganese dust on their work clothes.
