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.

In the process of calcination of manganese ores in air, MnO2 was reduced to Mn2O3 and Mn3O4, while during calcination in a reducing atmosphere manganese oxides were reduced to MnO and iron oxides to metallic iron. Formation of a liquid slag in ores at equilibrium was predicted for Wessels, Groote Eylandt and Gabonese ores at 1200°C in air and 1000-1200°C in a reducing atmosphere. No liquid slag was predicted for equilibrium phases in CVRD ore.

Manganese - Wikipedia

A more progressive extraction process involves directly reducing manganese ore in a heap leach. This is done by percolating natural gas through the bottom of the heap; the natural gas provides the heat (needs to be at least 850 °C) and the reducing agent (carbon monoxide). This reduces all of the manganese ore to manganese oxide (MnO), which is a leachable form. The ore then travels through
