Ilmenite - Sandatlas

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.
