How Manganese is Extracted and Refined A Quick Guide

Описание: 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. The higher oxides (MnO2, Mn2O3, and Mn3O4) 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. Smelting is further complicated by the action of the gangue oxides.
