Domestic perovskite (catio3) deposits represent a significant unutilized titanium resource. The Bureau of Mines investigated h2so4-catio3 reactions at atmospheric pressure for converting the titanium to water-soluble sulfates. Batch studies were conducted in an agitator-equipped glass vessel to determine the effect of certain variables on the sulfation rate. The sulfation rate improved with increased acidity, temperature, and agitation, as well as with decreased particle size and percent solids. Under some conditions, over 98% of the titanium was rapidly converted to water-soluble sulfates. It appears that acid sulfation can provide a feasible first step in processing perovskite concentrates.
