At temperatures above 1150°C, reduced iron forms a liquid alloy, dissolving carbon and assisting in the reduction of manganese due to lower Mn activity in the metal phase. Considerable smelting of the remaining oxide mixture starts at ~1250°C, and the final reduction of MnO to manganese metal will take place with solid carbon in the coke bed.
