Ilmenite deposits, a by-product of the tin industry in Bangka, cause environmental problems. Ilmenite is very abundant and has great potential because it still contains 53.83% titanium oxide. One of TiO 2 benefits is for pigment. TiO 2 pigment in Indonesia still imported. TiO 2 pigment can be applied to various industrial sectors such as paints, coatings, fillers, semiconductor materials. This research aims to extract TiO 2 from ilmenite with purity level above 80%. The TiO 2 extraction used repeated leaching methods with sulfuric acid. Then followed by the hydrolysis process with the addition of seed and calcined. TiO 2 products were analyzed using X-ray fluorescence (XRF) and X-ray diffraction (XRD). The content of TiO 2 obtained in this process is 83.36% and is in the form of rutile crystals. The purity and crystal formed of this TiO 2 product suitable with the minimum standards of TiO 2 pigments required by ASTM D 476 (2015). This research can be the alternative to solve environmental problems in the tin industry while increasing the economic value as TiO 2 products that has great market potential in Indonesia since there is no TiO 2 industry in Indonesia.
