Manganese-Ferroalloy Production from Russian Manganese Ore

摘要

Optimal technology for the production of manganese ferroalloys from Usinsk magnesium ore is developed. To that end, the chemical composition and the concentrates and the characteristics of ferroalloy smelting are analyzed. The proposed technology permits the production of standard manganese ferroalloys, without the need for imported manganese ores that are rich in manganese and low in phosphorus. The proposed technology is of strategic value in terms of national economic security and import substitution. Finally, attention turns to the possibility of increasing Russian production of high-carbon ferromanganese and ferro-silicomanganese on the basis of Russian manganese ore and developing production technologies for refined manganese ferroalloys (moderate- and low-carbon ferromanganese and metallic manganese) without reliance on imported ores.
