Abstract
A method (500) for producing a titanium product is disclosed. The method (500) can include obtaining TiO2-slag (501) and reducing impurities in the TiO2-slag (502) to form purified TiO2 (503). The method (500) can also include reducing the purified TiO2 using a metallic reducing agent (504) to form a hydrogenated titanium product comprising TiH2 (505). The hydrogenated titanium product can be dehydrogenated (506) to form a titanium product (508). The titanium product can also be optionally deoxygenated (507) to reduce oxygen content.
Claims26
A method for producing a titanium product, comprising:
- obtaining TiO2 rich material as a purified TiO2;
- reducing the purified TiO2 using a metallic reducing agent at a temperature and a pressure to produce a hydrogenated titanium product comprising TiH2 and optionally elemental titanium;
- and
- dehydrogenating the hydrogenated titanium product to form the titanium product.
A method of forming purified TiO2 from a TiO2 rich material comprising:
- pre-leaching the TiO2 rich material to remove silica to form a leached TiO2 rich material;
- alkaline roasting the leached TiO2 rich material to produce intermediate products including alkaline leached TiO2 rich material;
- washing the alkaline leached TiO2 rich material to form washed TiO2 rich material;
- hydrolyzing the washed TiO2 rich material to form a titanic acid;
- and
- calcining the titanic acid to form a coarse purified TiO2 as the purified TiO2.
