The reduction of Mn (2) : concerning the mixed carbide (Fe,Mn)3.C *According to Ellingham, the reduction of MnO to Mn metal by C is effective from a temperature of 1400C. This theoretical reaction is not confirmed in the blast furnace because it takes place in contact with an excess of solid C as metallugical coke.

Puddling (metallurgy)
This helps the oxygen from the oxides to react with impurities in the pig iron, notably silicon, manganese (to form slag) and to some degree sulfur and phosphorus, which form gases that escape with the exhaust of the furnace. More fuel is then added and the temperature is raised. The iron completely melts and the carbon starts to burn off.
