Abstract
Ferromanganese and silicomanganese were produced by carbothermic methods from the Denizli-Tavas manganese ores containing 43.4 % Mn. Reduction smelting experiments were carried out in a 270 kVA laboratory scale electric arc furnace. Ferromanganese containing 85.1% Mn, 1.0 % Si was produced by 82.1% manganese recovery with charge containing 16.7 % coke and 12.4 % CaO. Silicomanganese containing 69.7 % Mn, 18.2 % Si was obtained by using charge mixing of ore and silica sand containing 19.0 % coke with 70.7 % manganese recovery.
