Cheap, Environmentally Friendly Extraction Method For Titanium Dioxide Developed ScienceDaily (Feb. 13, 2008) — From medicine to make-up, plastics to paper - hardly a day goes by when we don't use titanium dioxide. Now researchers at the University of Leeds have developed a simpler, cheaper and greener method of extracting higher yields of one of this most useful and versatile of minerals. In powder form titanium dioxide (TiO 2 ) is widely used as an intensely white pigment to brighten everyday products such as paint, paper, plastics, food, medicines, ceramics, cosmetics - and even toothpaste. Its excellent UV ray absorption qualities make it perfect for sunscreen lotions too. Titanium dioxide, also known titania, is the naturally occurring oxide of titanium, the ninth most abundant element in the Earth's crust and the seventh most abundant metal. About 95% of titanium ore extracted from the Earth is destined for refinement into titanium dioxide and some 5.7 million tones of titanium dioxide is sold every year. TiO2 is also a precursor material for titanium metal production. In metal form it’s strong and
