Electrolytic manganese metal is the main material for producing manganese trioxide. In addition, due to its high purity and low impurities, it is an important alloying element for the production of stainless steel, high-strength low-alloy steel, aluminum manganese alloy, copper manganese alloy, etc. It is also an indispensable raw material for the production of welding electrodes, ferrites, permanent magnet alloy elements, and many manganese salts used in medical, pharmaceutical, and chemical industries; The newly developed damping alloy also requires electrolytic manganese metal. In recent years, the global aluminum industry has become the main user of electrolytic manganese metal. In the steel industry, electrolytic manganese metal is also used as a deoxidizer and desulfurizer. According to statistics, the average consumption of electrolytic manganese metal per ton of steel is 0.06kg.
With the advancement of metallurgical technology, efficient steel and spray metallurgy technology have made great progress. The application of electrolytic manganese powder in the metallurgical industry has been increasing day by day, and the amount has expanded, breaking through the above indicators. In recent years, due to the rapid development of special steel, especially the development of 200 series stainless steel in China, the proportion of manganese metal in metallurgy has been increasing. Aluminum manganese alloy is a modern lightweight and beautiful building material, decorative engineering material, and anti-corrosion support material for underground engineering.
Production process of Metal Manganese Alloy : Electrolytic manganese metal is a wet metallurgical product of manganese. In many years of production practice in China, the production process of "leaching purification electrolysis" is generally adopted. The main method is to react manganese carbonate powder with inorganic acid to produce manganese salt solution. Ammonium salt is added as a buffering agent, and iron is removed by adding an oxidizing agent for oxidation and neutralization. Heavy metals are removed by adding a sulfurizing agent. After "settling filtration deep purification filtration", a pure manganese sulfate solution is obtained. After adding additives, it is used as an electrolyte to enter the electrolytic cell for electrolysis, producing metallic manganese.

Electrolytic manganese and stainless steel
In steelmaking production, electrolytic manganese is particularly suitable for smelting "special, refined, and high" alloy steels such as stainless steel, heat-resistant steel, precision steel, high-temperature steel, and corrosion-resistant steel containing more than 10% of alloying elements, as well as pure steels with low impurities and low harmful elements (∑ P S、O、N、H≤100ppm)、 Pure steel (∑ P, S, O, N, H ≤ 200ppm) and other steel grades. According to the production and consumption level of electrolytic manganese in special steels such as stainless steel, high alloy steel, and high-quality steel in China, the smelting consumption of electrolytic manganese in China's stainless steel and other special steels was about 160000 tons in 2004; Among them, the consumption of chromium manganese stainless steel is about 80000 tons, and the excessive and abnormal consumption in chromium manganese stainless steel smelting is 20000 to 30000 tons; The consumption of steel grades such as chromium nickel stainless steel, chromium stainless steel, heat-resistant stainless steel, precision alloy steel, high-temperature alloy steel, corrosion-resistant alloy steel, and other special steels is about 50000 tons.
With the further adjustment and optimization of steel variety structure by steel enterprises, the production of high-quality steel with high added value and high technological content, such as stainless steel and special steel, will increase significantly in the future. Undoubtedly, the consumption of electrolytic manganese in the smelting of high-quality steel will also have a relatively large incremental space.
To grasp the development of the electrolytic manganese industry well, the situation of downstream manufacturers is naturally closely related. In addition to 200 stainless steel, electrolytic manganese is also used to produce special steel and high-quality steel, among which special steel can also be produced using manganese ingots or cheaper high carbon manganese iron. The global annual production of special steel requires 70000 to 80000 tons of electrolytic manganese, 10000 to 20000 tons of manganese for manganese aluminum alloys, and 50000 to 60000 tons of manganese for magnetic materials such as Mn3O4. The total global demand is about 450000 to 500000 tons
