Titanium dioxide - Wikipedia

Rutile is the second most abundant mineral sand. Rutile found in primary rock cannot be extracted hence the deposits containing rutile sand can be mined. Crude titanium dioxide (in the form of rutile or synthetic rutile) is purified by conversion to titanium tetrachloride in the chloride process. In this process, the crude ore.
