It was thermodynamically proven that rutile can spontaneously dissolve in H2SO4 solutions with the formation of salts Ti(SO4)2 and TiOSO4. The kinetic difficulties of the reactions of sulfuric acid dissolution of rutile should be explained by the features of Ti(IV) cation properties and the rutile crystal structure. The sodium fluoride additives intensify the reaction between sulfuric acid and rutile by reducing the activation energy to 45 kJ/mol. It was proposed to consider the decomposition of rutile by sulfuric acid in the presence of NaF additives as a homogeneous–heterogeneous catalytic process where fluoride ions play the role of a bifunctional catalyst.
