Abstract: The present invention is a process for controlling, at an aim point, the passivation of aluminum chloride in the chlorinator discharge stream in a process for making titanium tetrachloride.

Abstract: The present invention provides a process for recovering the chlorine value from a particulate feed stream of metal chlorides wherein the total energy and reactant mass flow are managed to minimize the build up of deposits of solids on the reactor walls and maximize the conversion of the metal chlorides to metal oxides and chlorine.

Abstract: A reduction/chlorination process is provided for the treatment of titaniferous materials such as ilmenite ores. The chlorination is selective in that the titanium constituent of the titaniferous material is chlorinated, but there is no appreciable net yield of iron chloride from the iron constituent. Where other metals such as vanadium are present they may be chlorinated with the titanium. The reduction utilizes as the reductant an amount of carbonaceous material which, based on oxygen in the titaniferous material, is at least stoichiometric to produce carbon monoxide. The selective chlorination utilizes as the chlorinating agent either ferrous chloride (FeCl.sub.2) alone or certain combinations of ferrous chloride and one or more other chlorine-containing members, notably molecular chlorine (Cl.sub.2) and hydrogen chloride (HCl). The use of ferric chloride (FeCl.sub.3) as a part or all of the chlorinating agent is the equivalent of using a FeCl.sub.2 /0.5 Cl.sub.2 mixture.
