So-called 'ilmenite', 'leucoxene' and 'rutile' grades of commercial heavy mineral concentrates were fractionated magnetically, in the laboratory. In the less magnetic fractions, secondary TiO2 (both anatase and rutile), formed by the alteration of ilmenite grains, was separated from primary rutile, on the basis of density. The separated fractions were examined by optical and scanning electron microscopy (SEM) and X-ray diffraction (XRD) methods, thereby insights being gained into the nature of secondary contamination in altered ilmenite. Grains of secondary TiO2 are very porous and report with an effective density
