Abstract
There is provided an improved process for chlorinating an iron-containing titaniferous ore, such as ilmenite which comprises dividing the ore charge into 2 parts. The first and major part is chlorinated with chlorine or with a mixture of chlorine and FeCl.sub.3 under fluidized bed conditions to yield principally TiCl.sub.4 and FeCl.sub.2. The FeCl.sub.2 is separated out and utilized as a chlorinating agent for the minor part of the ore in an entrained flow chlorinator to yield more TiCl.sub.4 and metallic iron as principal products. This process avoids the need for disposal of FeCl.sub.2 and retains the advantages of conventional chlorination procedures.
