manganese dioxide reduction by carbon

While manganese compounds was in widespread use among alchemists and glassmakers, it was only in 1774 when manganese as an element was first identified. Johan Gottlieb Gahn was the first one to isolate manganese via the reduction of dioxide with carbon. The metal has since then been used in a wide range of industrial and commercial uses.

manganese. Reduction is in the form of either metalothermic reduction or carbothermic reduction. Practically, metallographic reduction is performed with silicon or aluminium which form more stable oxides than magnesium. Carbothermic reduction means reduction with carbon. All of the reduction reactions are highly endothermic and a high amount of thermal energy

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).
