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
