Production processes. Ferroalloys 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 (metallothermic reduction), usually aluminium or silicon. High carbon ferromanganese is produced by the reduction of manganese ...
