A method for purifying with respect to iron, aluminum chloride produced via the chlorination of aluminum bearing ores or materials which also contain iron. The process comprising the steps of: 1. chlorinating the aluminum value containing material in a manner which produces a gaseous product containing both ferric chloride and aluminum chloride; 2. oxidizing at least a portion of the ferric chloride to particulate iron oxide; 3. removing the iron oxide from the gaseous product; 4. reducing any remaining ferric chloride to ferrous chloride, using reduced iron oxide, e.g. iron powder; 5. condensing the ferrous chloride along with at least about 10% of the available aluminum chloride to assure removal of substantially all iron chloride; and 6. condensing the remaining about 80% of the available aluminum chloride as pure product.
