Process for PURIFYING a Mineral of Titanium dioxide, which is found in nature as mineral anatase and anatase Titanium dioxide in the form of benefited through the process.

摘要

The present Invention relates to a process for the benefit of Titanium dioxide mineral that is found in nature in the form of anatase,Comprising: (a) contacting the mineral with an aqueous solution of a Mineral acid, which has a concentration of 3 to 30 percent by weight,The contact takes place at a temperature of approximately 160 to 300 Celsius degrees,Until the desired amount of impurities is Solubilized and form a alixiviado and (b) remove the leachate of the product of Step (a).
