A titanium dioxide compound was isolated from a rare type of naturally
occurring ore. Processes for efficiently isolating and obtaining these
TiO.sub.2 compounds, as well as methods for using them have been
developed. These TiO.sub.2 compounds may be used directly in applications
such as paper, plastics and paints without being subjected to the chloride
or sulfate processes. Also they made be used as a feedstock for the
chloride or sulfate processes. In order to obtain these TiO.sub.2
compounds, one may grind or pulverize the naturally occurring ore,
disperse it in a solution or suspension, and process it by selective
flocculation or aqueous biphasic extraction.
