Abstract (en)
Ferruginous titaniferous material having an iron to titanium molar ratio Fe/Ti of n:1, n being at least about 0,25 is chlorinated in the presence of carbonaceous reductants with not more than x + 2 moles of chlorine per gram atom of titanium, in a laminar flow at about 1050-1950 DEG C. The atomic ratio of carbon in the mixture to the oxygen content is greater than 1:1. A product stream of titanium chlorides and by-product metallic iron is withdrawn. In a preferred operational mode the reaction zone is followed by a hot separation zone and a cool separation zone.
