Abstract
The optimal decomposition of ilmenite to obtain an increase in TiO2 levels has been successfully carried out through a multi-step hydrometallurgical process. The initial levels of ilmenite in the iron sand was obtained about 46.50%. The multi-step hydrometallurgical process was carried out in order to determine the efficiency of TiO2 extraction. The sediment, which is obtained by this process was characterized using XRD and SEM-EDS. The result of XRD analysis was obtained the percentage of TiO2 formed in the leaching stage 1 and 2, respectively 85.01% and 95.55%. Based on the result of SEM-EDS analysis, the morphological was heterogeneous with particle size about 180-300 nm. It was concluded, that a multi-step hydrometallurgical process can increase TiO2 levels quite high and the process efficiency was very good
