Abstract
A process is set forth for reducing the aluminum carbide content of aluminum produced via carbothermic processes which comprises contacting the aluminum contaminated with aluminum carbide with reactive gases so as to cause the aluminum carbide to react and separate from the aluminum. The aluminum is recovered and the residue can be recycled back to the furnace without additional chemical treatment.
