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.

Oxidation of manganese(II) and reduction of manganese

01/11/2000 Decreasing acid concentration favours MnO 2 deposition while high acid concentrations inhibit the formation of MnO 2. The mechanism of MnO 2 deposition from Mn (II) is suggested to be an ECE sequence with the formation of an insulating intermediate (MnOOH). Small amounts of deposited MnO 2 may be reduced electrochemically at the electrode surface.

Practical reduction of manganese oxide.

Reduction of manganese oxides is considered in two steps. 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 MnO 3 and Mn 2 O 3 into MnO 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.
