A process for the recovery of titanium values from a complex matrix containing titanium nitride comprises chlorinating the titanium nitride in the matrix to obtain a reaction product containing titanium chloride, and separating the titanium chloride from the reaction product. The complex matrix containing titanium nitride may be obtained by nitriding titanium values in complex titanium-containing starting materials such as complex metallurgical titaniferous slags and ilmenite, perovskite, armalcolite and fassaite. The chlorination may be carried out at 200-500 DEG C with a chlorinating gas e.g. Cl2, HCl, CCl4, SCl2 or mixtures thereof. |
