AbstractThe dissolutionkinetic of NaxH2-xTiO3(resulting from high titanium slag treatment by NaOH) by diluted sulfuric acid (38 similar to 51 wt. %) was carried out in temperature range of 10 to 50 degrees C with an initial acid/NaxH2-xTiO3 (wt.) ratio of 1:1.The effects of the sulfuric acid concentration and temperature on titanium dissolution percent were reported, and both of them significantly affected the dissolution rate. The experimental data indicate that the shrinking core model controlled by diffusion in product layer is most applicable for the titanium dissolution process, and the apparent activation energy has been estimated to be 28.69 kJ/mol.
