'''Rutile''' reddish-brown to black tetragonal mineral; commonly massive or as long prismatic crystals. Its cleavage is distinct {' 110}; hardness is 6-6.5 on Moh's scale and specific gravity is 4.2-4.5. It is a common accessory mineral of acid igneous and metamorphic rocks and also occurs in quartz veins and as residual grain in beach sand. Rutile is mainly used to make welding rods, in the paint industry, and as a source of Ti metal.

In Bangladesh rutile is found as [[Beach Sand Heavy Mineral|beach sand heavy mineral]] placer deposits in the sea beaches and coastal islands of Cox's Bazar, Chittagong, Noakhali and Patuakhali districts. It occurs mostly with fine to very fine sand grains. Generally the [[Sand|sand]]s containing it are coarser than the sands containing zircon, magnetite and [[Monazite|monazite]]. The highest concentration of 4% of rutile is reported from Maheshkhali Island, the lowest concentration of 0.35% from Kuakata, as and the average is 2%. The reserve of rutile in Bangladesh is about 70,274 thousand tons. [Sifatul Quader Chowdhury]
