Ilmenite - Chemeurope.Com
Distinguishing features . ilmenite is often recognised in many altered igneous rocks (which is most, to some extent) by the production of the white pseudo-mineral leucoxene.often, ilmenites are rimed in leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. the example shown in the image at right is typical of leucoxene-rimed ilmenite.

Ilmenite – Creative Generation
Ilmenite is an iron titanium oxide, it is the principal ore of titanium. it is black (or dark gray) and has a metallic luster. it is usually weakly magnetic. the mineral itself is actually not magnetic but it is often intergrown with magnetite, which very strongly responds to the magnetic force. you can use a hand-held magnet to test sand grains.
