    摘要: The present invention provides a method of refining aluminum, according to which oxygen gas is blown into a carbon material filled in a blast furnace to form simultaneously both combustion regions where combustion of the carbon material takes place and high-temperature reduction regions spaced apart from said combustion region, and an alumina-containing material and a flux are fed on the carbon material fill layer to form a melt of a mixture of the both, the formed melt being flowed down to the reduction regions to form a crude aluminum alloy, which is hydrogenated.
