electrolytic manganese Description
In foreign steel industry, electrolytic manganese is also used as deoxidizer and desulfurizer. According to statistics, the average consumption of electrolytic manganese per ton of steel abroad is 0.06kg. With the advancement of metallurgical technology, high-efficiency steel and jet metallurgy technology have been greatly developed. The application of electrolytic manganese powder in the metallurgical industry has increased day by day, and the amount has expanded, breaking through the above indicators. In the past five years, the world aluminum industry has become the main user of electrolytic manganese. Taking Japan as an example, electrolytic manganese is used for aluminum alloy production, accounting for 58%, and for special steel production 38%, and other industries account for only 4%. In recent years, due to the rapid development of special steel, especially the development of 200 series stainless steel in my country, the proportion of manganese in metallurgy has become larger and larger. Aluminum-manganese alloy is a modern light and beautiful building material, decorative engineering material and anti-corrosion support material for underground engineering. In recent years, aluminum-manganese alloy doors and windows in China have gradually entered ordinary residential buildings, greatly expanding the market for manganese.
Electrolytic manganese metal production process: Electrolytic manganese metal is a hydrometallurgical product of manganese. In the domestic production practice for many years, the production process of "leaching-purification-electrolysis" is generally adopted. It mainly uses manganese carbonate powder to react with inorganic acid to obtain manganese salt solution, adds ammonium salt as a buffer, uses oxidant oxidation neutralization method to remove iron and adds sulfidizer to remove heavy metals, and obtains pure manganese sulfate solution through "sedimentation-filtration-deep purification-filtration". After adding additives, it enters the electrolytic cell as electrolyte for electrolysis to produce metallic manganese.
