laboratory conditions during reduction of 1 kg of manganese ore concentrate, was approximately 2300 K. The standardchange in Gibbs energy of the aluminothermic reduction of monoxide manganese at the given temperature was calculated from the data in [6].
requires [2]. The reduction reaction of oxides by aluminum can be generally, represented by the following equation [3]: 2/y MxOy + 4/3 Al = 2x/y M + 2/3 Al2O3 (1) Where MO represents the reducible oxides in the ore or concentrate. The most important consideration with development of satisfactory aluminothermic reaction is that the

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.

Aluminothermic reactions are exothermic chemical reactions using aluminium as the reducing agent at high temperature. The process is industrially useful for production of alloys of iron. The most prominent example is the thermite reaction between iron oxides and aluminium to produce iron itself: . Fe 2 O 3 + 2 Al → 2 Fe + Al 2 O 3. This specific reaction is however not relevant to the most ...
