A method of producing an aluminum metal from alumina, silica and iron oxide bearing materials by mixing the coal and bringing the mixtures to the temperature in the range of 600 DEG to 900 DEG C. in order to make the alumina bearing coked briquettes. Then, the coked briquettes are brought to the temperature in the range of 2,000 DEG to 2,100 DEG C. to produce aluminum, silicon and iron containing alloys. The alloys are scrubbed by molten lead spray directly after the alloys formation, and are converted to lead-aluminum alloy. An aluminum is separated from lead by liquation and purified by fractional distillation. |
