The modern name "manganese" was derived from the 16 th century name for manganese dioxide, manganesum. The pigments from several colored manganese oxides, such as manganese dioxide, have been used by men since the Stone Age, as is the case in the Gargas cave paintings. These have been dated as 24,000 to 30,000 years old.

Manganese Redox - Explorechem

Pure manganese is produced by hydrometallurgical and electrolytic processes, while ferromanganese and silicomanganese are produced by the smelting of ores in a blast furnace or, more commonly, in an electric furnace. The latter process, involving the reduction of manganese oxides by carbon, is actually a complex thermodynamic problem.

May 01, 2018· The reduction of manganese dioxide by sulfur is feasible. Manganese dioxide was reduced stepwise to low-valence state in the order of MnO 2 → Mn 2 O 3 → Mn 3 O 4. Subsequently, Mn 3 O 4 would be reduced to form MnS or MnO (together with MnSO 4 or SO 2), and the tendency of forming MnO was enhanced with increase in the roasting temperature.
