PRODUCTION OF MANGANESE FERROALLOYS FROM DOMESTIC MANGANESE ORES

This paper studies the possibility and proposed optimal technological scheme of manganese ferroalloys of manganese ores from Usinskoye deposit on the basis of analysis of the concentrates chemical composition and indicators of manganese ferroalloys smelting processes. It is shown that the standard manganese ferroalloys can be produced without attracting the rich content of manganese, low-phosphorous import manganese ore. The solution of this problem is of strategic importance from the standpoint of economic security and import substitution of manganese resources. The authors actualized the direction, allowing to explore opportunities not only to increase the volume of melt in the Russian high-carbon ferromanganese and ferrosilicon manganese, including through the involvement in the domestic production of manganese ore, but also to develop import-substituting technology for the production of refined manganese fer-roalloys – medium and low carbon ferromanganese and manganese metal from these ores.
