The invention concerns a method of obtaining manganese alloys with an average carbon content by reacting liquid, carbon-containing ferro-manganese in a fluid tight chamber. Oxygen, mixed with a heat regulating gas such as CO2, air, nitrogen, argon or steam, is introduced and by controlling the discharge of the gaseous effluent, the pressure in the reactor is adjusted between 1.5 and 15 bars, to avoid volatilization of the manganese and a refined ferro-manganese is produced containing 0.5-2% carbon.
