This invention provides a process for the recovery of titanium values from a complex matrix comprising titanium nitride. The process 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 invention also provides for the production of said complex matrix containing titanium nitride by nitriding titanium values in complex titanium-containing starting materials such as complex metallurgical titaniferous slags and ilmenite, perovskite, armalcolite and fassaite.
L'invention porte sur un procédé pour la récupération de titane à partir d'une matrice complexe renfermant du nitrure de titane. Le procédé consiste à chlorer le nitrure de titane dans la matrice, de façon à obtenir un produit de réaction renfermant du chlorure de titane, et à séparer ce chlorure du produit de réaction. L'invention porte également sur la production de la matrice complexe renfermant le nitrure de titane, par nitruration des composés titanifères dans les matières de départ complexes, comme le laitier métallurgique, l'ilménite, la pérovskite, l'armacolite et la fassaite.
