Abstract: A process is provided for removing impurities from a slurry of titanyl hydrate. The titanyl hydrate is separated from the slurry, washed, and reslurried with water to make the resulting titanyl hydrate slurry fluid. The reslurried titanyl hydrate slurry is then treated by the addition of a trivalent titanium compound in an amount between about 0.01 grams and about 0.7 grams trivalent titanium compound measured as TiO.sub.2 per 100 grams titanyl hydrate as calcined TiO.sub.2 in the absence of additional acid values. The titanyl hydrate is then separated from the treated slurry, washed and recovered.
