Manganese processing Britannica

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.
