2018-6-19 Ferro-manganese (Fe-Mn) is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron (Fe) and manganese (Mn) with a minimum Mn content of 65 %, and maximum Mn content of 95 %. It is produced by heating a mixture of the oxides of Mn (MnO2) and iron (Fe2O3) with carbon (C) normally as coke or coal.

Reduction roasting of manganese ore is the first step in the extraction of the metal, production of manganese based chemicals and benefaction of ferruginous manganese ores. In comparison to the conventional processes, the invented process replaces the expensive petroleum based reductant injected with air by cheap solid carbonaceous material and sealing of air entry.

2014-1-1 As the raw materials move down the furnace, the higher oxides of manganese are reduced to MnO by the gas leaving the furnace. The reduction of manganese(II) oxide occurs by the contact of carbon with the molten oxide in the slag phase. The overall reaction is: (1.10.70) MnO + 10 7 C → 1 7 Mn 7 C 3 + CO for which (1.10.71) Δ G° = 265.7 − 0 ...

Until today, the producers of ferromanganese in the blast furnace (Dancoisne, 1977, Truffaut 1989 - 1994) are responsible for the tradition that to reduce MnO, it is necessary to reach the temperature of 1410 ° calculated by Ellingham In fact, it is impossible to reduce manganese oxide MnO as metallic manganese Mn. The blast furnace standard ...
