摘要： Enriched titanium hydrochloric acid extract residue is provided, for use as the feed stock in the preparation of titanium pigment by sulfuric acid process. The present invention belongs to the field of the preparation of titanium pigment and particularly, relates to the enriched titanium hydrochloric acid extract residue prepared from ilmenite by hydrochloric acid leaching, its use and the method of preparing titanium pigment. The method for preparing titanium pigment using the enriched titanium hydrochloric acid extract residue can effectively utilize the fine ilmenite in Panxi area (the utilization rate is almost 100%), obtain the titanium sulfate solution with an ultralow ratio of iron to titanium dioxide (Fe/TiO2) and double the throughput of digesting equipment. Said method can simultaneously spare two steps of iron removal by freezing and titanium sulfate solution concentration with much energy consumption, reduce the times of washing with metatitanic acid, thereby, both of the discharge of acid waste water and the production of FeSO4 are reduced. Said method provides a feed stock selection for preparing titanium pigment by sulfuric acid process.

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.
