The extraction of manganese from the tailings slag obtained in the production of refined manganese ferroalloys is studied thermodynamically and experimentally. In such extraction, the slag reacts with metal melts (hot metal, ferromanganese, and ferrosilicomanganese) containing reducing elements (carbon and silicon), with the goal of increasing the overall transfer of manganese to the final manganese...
To extract manganese from the tailings slag produced in the furnace smelting of manganese with silicon, a possible approach is to reduce the slag by means of melts of iron, high-carbon ferromanganese, or ferrosilicomanganese. Thermodynamic analysis of this process is undertaken. The reaction of these melts with the slag is also studied experimentally. It is found that the reduction of manganese from...
