A method for pelletizing the fine-dispersed manganese concentrates involves obtaining manganese carbonate by precipitation from the manganese sulphate solution with ammonium carbonate, washing and filtration of manganese carbonate, subsequent compression with external vibrator. The compressed manganese carbonate is burned in the electric furnace with induction magnetic field, which induction frequency is of 50 Hz, burning temperature of 850 centigrade degrees, burning time is of 20-25 minutes.
