    Steelmaking - Wikipedia

    Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

    Why Manganese Ore Is Consumed In Blast Furnace

    Why Manganese Ore Is Consumed In Blast Furnace. Pure manganese is produced by hydrometallurgical and electrolytic processes, while ferromanganese and silicomanganese are produced by the smelting of ores in a blast furnace or, more commonly, in an electric furnace. the latter process, involving the reduction of manganese oxides by carbon, is actually a complex thermodynamic problem.

    The ascending gases start to reduce the iron oxide of the burden in the upper portion of the blast furnace where the temperature is below 925 deg C. At this temperature, chemical equilibrium prevents all the CO and H2 fro being used for reduction (the equilibrium CO/CO2 ratio is around 2.3 for the reduction of FeO, if the ratio falls below 2.3 than iron is reoxidized).
