On the other hand, reduction reactions of the higher manganese oxides (MnO x, where x > 1) with CO gas are all exothermic. For instance, about 20% energy reduction for this process might be achieved if the Mn 3 O 4 sinter is fully replaced by MnO 2 ore. The addition of carbonate ores leads to higher energy consumption, as might be expected.
