-19- ABSTRACT The invention relates to the recovery of chlorine values as ferric chloride from iron chloride dust which is obtained as a by-product from the chlorination of a titaniferous material containing more than 5% by weight iron oxide, such as ilmenite. The method comprises heating the iron chloride dust to a temperature above 275°C in the presence of chlorine and iron oxide and recovering the ferric chloride volatilised from the iron chloride dust together with the ferric chloride obtained from ferrous chloride present in the iron chloride dust by reaction with the chlorine and ferric chloride obtained from other metal chloride contaminants by reaction with the iron oxide.
