ABSTRACT In the carbothermic reduction of alumina evolved carbon monoxide has a high content of Al fume and Al2O. A substantial part of this fume is recovered by allowing the temperature of the CO gas to fall by 50-150°C during passage through a moving bed of carbon particles at a temperature of 50-150°C. The carbon particles move through the bed in either co-current or counter-current direction in relation to the CO gas and such bed may be retained in an enclosure which is rotatable about a vertical axis to a body of molten alumina, which lies beneath it. Solid alumina may also be introduced into the carbon particle bed. This is conveniently done by introducing the alumina particles into the top end of the bed with a downwardly flowing CO gas stream.
