PROCESS FOR THE RECOVERY OF TITANIUM VALUES, MATERIAL CONTAINING TITANIUM VALUES, PROCESS TO PRODUCE A COMPLEX MATRIX UNDERSTANDING TITANIUM NITRIDE AND COMPLEX MATRIX

摘要

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.
