Effect of Fe on Carbothermic Reduction of MnO
ISIJ International, 2016 The effect of Fe addition on the carbothermic reduction of MnO has been investigated from kinetic viewpoint in the temperature ranges of 1 100-1 300 degrees C. The addition of Fe affected the carburization rate of MnO at all the experimental temperatures. The reduction degree and carburization rate of MnO were increased with adding metallic Fe, and the
