Abstract
There is provided a multi stage process for nonselectively chlorinating a titaniferous ore containing iron to produce TiCl.sub.4. In this process a portion of the ore charge is subjected to conventional fluid bed chlorination to produce TiCl.sub.4 and FeCl.sub.2. A second portion is subdivided and submitted to chlorination in a dilute phase chlorination step using FeCl.sub.3 as the chlorinating agent to produce additional TiCl.sub.4. The FeCl.sub.3 is obtained by partial oxidation of the FeCl.sub.2 obtained in the first stage and/or second stage to yield Fe.sub.2 O.sub.3 and FeCl.sub.3. The product streams of TiCl.sub.4 are then combined for further treatment.
