In this research for the first time in Iran, the anatase crystallographic structure of titanium dioxide was produced from the ilmenite concentrate from the Kahnooj mine by the sulphate method .The raw material contained 47.9 w% of titanium dioxide. By several experiments including grinding and drying, digestion, dissolution and reduction, crystallization, hydrolysis, purification of the hydrolyzate and calcination stages, titanium dioxide was produced. In these experiments, the calcination temperature of 650 5ºC was found suitable for producing anatase crystallographic structure. The samples obtained from performing the experiments for three times were analysed by XRD and XRF. According to the results, three products have anatase crystallographic structure of TiO2 and the purity of 97.95, 96.03 and 96.39 w%. Regarding the high purity of them and low percentages of undesirable impurities, the final products obtained from the ilmenite concentrate from the Kahnooj mine by the sulphate method, could be applicable as a coloring agent and opacifier for glazes.
