In iron and steel industry, electrolytic manganese metal is also used as deoxidizer and desulfurizer. In recent years, due to the rapid development of special steel, the proportion of metallic manganese in metallurgy is increasing. Al-Mn alloy is used as modern light and beautiful building materials, decorative engineering materials and anti-corrosion supporting materials for underground engineering. China electrolytic manganese is not only the first in the world in terms of capacity and output, but also the first in terms of technical indicators such as current efficiency and metal recovery rate. Electrolytic manganese industry is an industry with high consumption of resources and energy and heavy environmental pollution. However, electrolytic manganese in China ranks first in the world not only in capacity and output, but also in technical indicators such as current efficiency and metal recovery rate. China's industrial technicians are constantly improving in technological innovation, cleaner production and pollution prevention and control.
