Production processes
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 ...
