摘要：
A titanium dioxide compound was isolated from a rare type of naturally occurring ore. Processes for efficiently isolating and obtaining these TiO2 compounds, as well as methods for using them have been developed. These TiO2 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 TiO2 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.
