Rutile may be separated from ilmenite or ilmenite ores by agitating a mixture of ilmenite and rutile in particle form in an aqueous solution containing a collection agent to which hydrogen peroxide has been added. The slurry in agitated form is treated with air to produce a froth. The ilmenite particles will attach themselves to the air bubbles in the …
Titanium Dioxide for Coatings ... crystal structures—anatase and rutile. Rutile TiO 2 pigments are preferred because they scatter light more efficiently, are more stable and are more durable than anatase pigments. Titanium dioxide pigments are insoluble in coating vehicles in which they are dispersed; accordingly, performance properties, e.g., …
