More DetailsALUMINOTHERMIC REDUCTION Table 1 gives the heat balance for aluminothermic reduction for manganese oxides. It may be observed that when the ore is used as its is, i.e., MnO,, the reaction is violent because the heat available is much more than the heat required. Also if the are is reduced to IMO stage the material become more inert.
