ilmenite rutile production

Rutile (TiO 2) was produced at room temperature from mineral ilmenite (FeTiO 3) by high energy ball milling of an ilmenite-sulphur mixture.A mechanochemical reaction, sulphurisation of iron in ilmenite producing TiO 2 and FeS 2, occurred during the milling process.During the subsequent annealing, the nanocrystalline TiO 2 obtained from milling recrystallised and FeS 2 decomposed at 600°C.
