Titanite rock ores are mostly produced in the form of titanomagnetite-ilmenite. Major origins are Canada, China, India and Russia. Titanium placers, also called titanium sands, are mostly produced in the form of ilmenite-rutile. Most of the titanium sand mines are dominated by ilmenite, and a few are dominated by rutile.
