Study the kinetics involved in solid state reduction of mill
2021year1month1day 1. Introduction. The coal-based direct reduction process produces metallic iron from ferric oxide under the solid-state. Normally it is observed that when the reaction temperature is low, the reduction rate will be slow [1].On the other hand, when the reaction temperature is too high, it is prone to bond and will cause a waste of energy.
