Ilmenite ore (FeO.TiO2) is source of titanium dioxide (TiO2) production. Titanium dioxide occurs in polymorphic forms as rutile,and anatase phase. InIndonesia,ilmenite sand was found in Bangka island.Modification ofa commercialprocesscapable to produceTiO2 high grade fromilmenite. In this research, the production of TiO2 from ilminite had been conducted and resulted the excellent procedure through roasting and leaching process. Result ofthehydrochloric acidleachingofroastedilmenitedepositedgraduallyin order to obtainTiO2.Fine crystallite anatasephase TiO2was generatedthroughco-precipitation processes using hydrolysis and condensation route via titanium isopropoxide complexes formation. Further hydrolisis process in 2-propanol-water of 9:1 v/v solvent ratio produce the anatase TiO2.
