Titanium Dioxide is manufactured in two crystal forms: Rutile and Anatase. It is obtained primarily from slag by two different processes: Sulfate and chloride.

The slag is treated with sulfuric acid, and later, the resultant titanyl sulfate is hydrolysed to form a hydrate. Both the sulfate and the chloride process produce rutile crystalline forms, but only the sulfate process produces anatase Titanium Dioxide, the form that is preferred for food, drug and cosmetic use.
