ABSTRACT:
A carbothermic process for producing an aluminium carbide containing mass by injecting carbon and alumina into molten aluminium superheated above 1400° C. The carbon reacts with molten aluminium to produce an aluminium carbide and alumina mass. The mass can be heated in the range of 1700° C. to 2000° C. to produce aluminium metal and carbon monoxide.
