ABSTRACT:
Titanium metal values may be recovered from a titanium bearing source such as an ilmenite ore by subjecting the source to a reductive roast and leaching the reduced source with a halogen containing compound such as hydrochloric acid. The soluble titanium halide is then extracted from the leach liquor by utilizing an organophosphoric acid such as mono-2-ethylhexylphosphoric acid. The extracted titanium may then be stripped from the loaded organic acid solution by treating the solution with a mixture of hydrogen peroxide and an inorganic acid. Thereafter the desired titanium metal value may be recovered from the acid solution by any means known in the art such as hydrolysis.
