Abstract
Aluminium chloride contaminated with iron chloride is purified by contacting it in vapor form with a bed of particles of aluminium metal interspersed with particles of a chemically inert material. The efficiency of the process may be maintained by acid treating, drying and recycling the bed material. The process may be applied to aluminium chloride produced by the chlorination of a bauxite beneficiate.
