Metal powders are prepared by electrolysis atomization and ball milling. All of them are physical changes, so electrolytic manganese is manganese powder.Electrolytic manganese metal is the main material for manufacturing manganese trioxide. In addition, because of its high purity and low impurity, it is an important alloy element for producing stainless steel, high strength low alloy steel, Al-Mn alloy, copper-manganese alloy, etc. It is also an indispensable raw material for welding rod, ferrite, permanent magnet alloy element, and many manganese salts used in pharmaceutical and chemical industries. Manganese.
Electrolytic Manganese Metal Production Process: Electrolytic Manganese Metal is a hydrometallurgical product of Manganese. In many years of domestic production practice, the production process of "leaching - purification - electrolysis" is generally adopted. Manganese sulfate solution was prepared by reaction of manganese carbonate powder with inorganic acid, ammonium salt was added as buffer, iron was removed by oxidizing neutralization with oxidant, heavy metal was removed by sulfurizing agent, and pure manganese sulfate solution was obtained by "sedimentation-filtration-deep purification-filtration". After adding additives, manganese sulfate solution was electrolyzed as electrolyte to produce manganese metal.
In iron and steel industry, electrolytic manganese metal is also used as deoxidizer and desulfurizer. According to statistics, the average consumption of electrolytic manganese metal per ton of steel is 0.06kg. With the progress of metallurgical technology, high efficiency steel and spray metallurgical technology have been greatly developed. The application of electrolytic manganese powder in metallurgical industry has been increasing day by day, and the consumption has expanded, breaking through the above indicators.
