ABSTRACT:
The invention relates to a method of recovering the chlorine values from iron chloride obtained from the chlorination of an aluminous material containing iron oxide, such as bauxite. The method involves partially dechlorinating ferric chloride in the presence of a reducing agent to form products comprising ferrous chloride and a chloride compound derived from the reducing agent and oxidizing ferrous chloride at a temperature of about 300.degree. C. to 1200.degree. C. to form products comprising ferric chloride and ferric oxide. The ferric chloride is recycled and the chlorine values are recovered as the chloride of the reducing agent which is suitable for recycle to the aluminous chlorination stage or has other industrial utility.
