ilmenite specification
Ilmenite is found in igneous and metamorphic rocks although it very rarely forms a major component of a rock. If that happens (in iron- and titanium-rich magmatic cumulates) then ilmenite is usually mined for its titanium content. Titanium extracted from ilm. in the form of titanium dioxide is used as a white pigment in paints and sunscreens among other things. Millions of tonnes of ilmenite are mined every year, but the majority of ilmenite comes from sand, not from the hard rocks.
