| Abstract: |
| The Ti-enriched slag was prepared, and the influence of sulfuric acid concentration, reaction time and reaction temperature on acidolysis rate of titanium dioxide were studied by single factor and orthogonal experiment. The results show that the factors sequenced according to the significant level were sulfuric acid concentration, reaction temperature and reaction time. The optimum acidification conditions include the reaction temperature of 180 ℃, reaction time of 140 min, and the sulfuric acid concentration of 95%, under these conditions, the acidolysis rate of titanium dioxide reaches 96.32%. |
