Aluminothermic Reduction of Manganese Oxide from

The aluminothermic reduction process of manganese oxide from different slags by aluminum was investigated using pure Al and two types of industrial Al dross. Two types of MnO-containing slags were used: a synthetic highly pure CaO-MnO slag and an industrial high carbon ferromanganese slag. Mixtures of Al and slag with more Al than the stoichiometry were heated and interacted in an induction ...

Manganese ore for Ferro Studies on Aluminothermic

2011-3-30 · ALUMINOTHERMIC 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.
