Owing to their high refractive index, titanium dioxide pigments impart whiteness, opacity and brightness to paints, paper, rubber and plastics.
Star sapphires and rubies owe their asterism starlike rays of light observed when some minerals are viewed from certain directions to inclusions of rutile within their crystalline structure. The naturally formed layer imparts a metallic gray color, but heat or electrochemical treatments can influence the thickness of the oxide layer, resulting in different colors.
Visit minerals. With higher grades of raw ore and scattered resource locations, titanium placer minerals mainly occur in Australia and the US. South Africa is abundant in both rock minerals and placer minerals. Rutile and ilmenite are extracted from sands that may contain only a few percent by weight of these minerals. After the valuable minerals are separated, the remaining sands are returned to the deposit and the land recultivated.
In the United States, titanium-rich sands are mined in Florida and Virginia. World titanium reserves Titanium is obtained from various ores that occur naturally on the Earth.
World resources of anatase, ilmenite and rutile total more than 2 billion tonnes. Identified reserves total million tonnes ilmenite plus rutile. The total world reserves of ilmenite are around million tonnes while rutile reserves are far less, numbering about 48 million tonnes.
