IRON REMOVING FROM TITANIUM SLAG FOR SYNTHETIC RUTILE …

Abstract. Leaching with sulfuric and hydrochloric acids for upgrading titanium slag obtained from the Qara-aghaj ilmenite concentrate to a high grade titanium dioxide (TiO2) was studied. The titanium slag containing 72.7% TiO2 and 7.8% Fe2O3 was leached at varying solid/liquid (S/L) ratio, particle size, leaching time and acid concentration. The optimum amount of S/L ratio, particle size, acid concentration and leaching time using both acids were determined as 1:4, -100 m, 8% and 2 h. Under optimum conditions, by using sulfuric acid, a titanium dioxide concentrate with 86.8% TiO2 and 1.87% Fe2O3 was produced, while employing hydrochloric acid resulted in a concentrate containing 91% TiO2 and 0.61% Fe2O3. The titanium dioxide …
