DetailsTitanium Overview. Titanium has played a major part in the history of the world from the mid 20th century up until today. It was discovered in the 1700s, produced in small quantities until the late 1800s, and finally went into commercial production once the Kroll process was devised and the militaries of different countries started to understand its importance.
DetailsJust 5% of all titanium ore mined is processed into titanium metal. The remaining 95% is used to manufacture brilliant white titanium dioxide pigment. Its colour stems from its high refractive index and it is used in everything from sun cream to the lines on Wimbledon's Centre Court to the sprinkling on Krispy Kreme's doughnuts.
DetailsBesides these compounds, bauxite contains iron oxide, which usually gives it a reddish-brown colour, as well as silicates (clay, quartz) and titanium oxide. The crys-tal structure also contains 12–20% by weight of water. Tropical monohydrate bauxite grades yielding 35–55% Al 2 O 3 will no doubt continue to be the most favored aluminum ores for
