ABSTRACT:
This invention provides a method of smelting aluminum by using a blast furnace. An oxygen gas is introduced into a carbon material packed in a reactor, to burn the same to form a plurality of raceways and a high-temperature reduction region among the raceways. A mixture containing an alumina-containing starting material and a carbon material is then supplied selectively into the high-temperature reduction region while substantially preventing the mixture from contacting the raceways, to reduce the alumina to aluminum.
