Production processes. Ferro-alloys are usually produced by the reduction of a metallic ore (generally oxide) by carbon with the addition of electric energy in a "Submerged Arc Furnace" (smelting process); or by metals (metallo-thermic reduction), usually aluminium or silicon. High carbon ferro-manganese is produced by the reduction of manganese ...
The quality of manganese ore used in smelting, that is, the content of manganese, iron, and phosphorus, and the composition of the gangue are very important.
