Industrial production of manganese begins with the extraction and processing of ores.

If manganese carbonate ore is used, then it is preliminarily subjected to roasting.

In some cases, the ore is further subjected to sulfuric acid leaching.

Then usually the manganese in the resulting concentrate is reduced with coke (carbothermic reduction).

Sometimes aluminum or silicon is used as a reducing agent.

For practical purposes, ferromanganese is most often used, obtained in the blast furnace process when reducing iron and manganese ores with coke. Ferromanganese has a carbon content of 6% to 8% by weight.

Pure manganese is obtained by electrolysis of aqueous solutions of manganese sulfate MnSO4, which is carried out in the presence of ammonium sulfate (NH4) 2SO4.

Application Manganese
Manganese in the form of ferromanganese is used to "deoxidize" steel during its smelting, that is, to remove oxygen from it. In addition, it binds sulfur, which also improves the properties of steels. The introduction of up to 12 - 13% Mn into steel (the so-called Hadfield Steel), sometimes in combination with other alloying metals, greatly strengthens the steel, makes it hard and resists wear and impact (this steel sharply hardens and becomes harder upon impact). Such steel is used for the manufacture of ball mills, earthmoving and stone crushing machines, armor elements, etc. Up to 20% Mn is added to the "mirror cast iron".
