Abstract

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 such slag by carbon from hot metal is promising for practical purposes. Hence, the overall extraction of manganese may be increased if the tailings slag from furnace smelting of manganese is used to alloy hot metal with manganese.
