ABSTRACT:
A mixture of an aluminous ore and a carbon source is dried and calcined in the presence of a sulfur-containing compound. The mixture is then chlorinated to produce crude metal chlorides. Aluminum chloride is condensed and separated from the remaining metal chlorides, combined with sulfur and aluminum powder, and sublimated and desublimated so as to produce substantially pure aluminum chloride.
