Manganese processing Britannica

The latter process, involving the reduction of manganese oxides by carbon, is actually a complex thermodynamic problem. The higher oxides (MnO 2,Mn 2 O 3,and Mn 3 O 4 ) can all be reduced to manganous oxide (MnO) by carbon monoxide,but this lower oxide can be reduced to the metal only at elevated temperatures by carbon.

Practical reduction of manganese oxide

The first step is the reduction of oxygen-rich oxides to MnO and the second one is the reduction of Mn to metallic manganese. Reduction starts with the transformation of MnO 2 into Mn 2 O 3 and Mn 2 O 3 into Mn 3 O 4 at temperatures over 450°C, then these two phases are reduced by either carbon or carbon monoxide in the system of Mn-C-O.

Manganese does not present a danger to human health, nor for the environment but it is unpleasant. In fact, the water gets a black color and a metallic taste. Similar to iron, the manganese removal by physical-chemical way, can be carried out by the oxidation of Mn 2+ in Mn 4+,which precipitates then in manganese dioxide (MnO 2 ).
