ABSTRACT:
An economic, non-polluting vapor-phase system of extracting titanium values from titanium ore or slag comprises solubilizing titanium (in ore or slag) with sulfuric acid to form titanyl sulfate, hydrolyzing the titanyl sulfate to form titanium oxide hydrate, converting the latter to pigment, and recycling sulfuric acid for extracting titanium values from further ore or slag. Methodology and equipment are provided.
