Manganese metal can be extracted in two main ways: thermally (pyrotechnic method) and electrolytically (wet method). Thermal production (manganese metal) has a purity of no more than 95-98 per cent, whereas pure manganese metal is prepared by electrolysis (electrolytic manganese metal), which can have a purity of more than 99.7-99.9 per cent. Electrolytic production has become the main method of manganese metal production.

Manganese and manganese alloys are one of the important and indispensable raw materials for the iron and steel industry, aluminium alloy industry, magnetic material industry and chemical industry.Electrolytic manganese is very pure, its role is to increase the hardness of the combined metal materials, the most widely used are manganese-copper alloys, manganese-aluminium alloys, 200-series stainless steel, manganese in these alloys can improve the alloy’s strength, toughness, wear resistance and corrosion resistance.
Manganese is an indispensable additive in the smelting industry, electrolytic manganese is the main raw material for the production of manganese tetraoxide after being processed into powder, and the magnetic material originals widely used in the electronic industry are produced by manganese tetraoxide, which is needed in the electronic industry, metallurgical industry and aerospace industry. With the continuous development of science and technology and the continuous improvement of productivity level, electrolytic manganese metal, due to its high purity and low impurity characteristics, has been successfully and widely used in various fields such as iron and steel smelting, non-ferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, electrode industry, aerospace industry, and so on.
