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.

Oxidation using oxygen only reaches an appreciable rate when the pH rises above 9.5 (figure 31). Mn 2+ oxidation using oxygen depends on temperature: oxidation will be 5 times faster when the temperature rises from 11°C to 22°C; however, at normal pH levels, contact times are not easily compatible with industrial operation.. The presence of manganese dioxide "catalyses" the reaction.
