Manganese processing | Britannica
Extraction and refining 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.
extraction of manganese
Extraction of Manganese. Prior to the use of electric arc furnace, ferromanganese was produced in mini blast furnace. But the composition was not controlled properly in the blast furnace. High grade ferroalloys are produced by adjustment the composition in
Locating and Estimating Sources of Manganese
