The fusibility difference between the manganese silicates slag and molten iron or iron carbides is the key point for the separation of Mn and Fe. The high temperature reduction and smelting separation procedures are conducted in one furnace, such as the blast furnace (BF) or electric arc furnace (EAF).

Blast furnace slag is a calcium-silicate-based product removed from the top of molten iron during its extraction from ore in a blast furnace. Usually, it is rapidly cooled to a glassy state and ground for use in construction materials (Provis et al., 2015). By the step of water quenching and out of rapid decrease in temperature, most of the ...

Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent. The carbon is fed to the blast furnace in the form of coke ( pyrolyzed coal) from the coking plant.
