All About Titanium

Titanium metal is therefore produced commercially by the Kroll process, a complex and expensive batch process developed in 1946 by William Justin Kroll. In the Kroll process, the oxide is first converted to chloride through carbochlorination, whereby chlorine gas is passed over red-hot rutile or ilmenite in the presence of carbon to make TiCl4.

Rutile - digitalfire.com

Rutile is the mineral name for natural crystals of titanium dioxide. However in nature rutile is always contaminated by up to 15% other minerals (especially iron but also things like tantalum, niobium, chromium and tin, the analysis provided here is obviously a simplification of the real picture). The term 'rutile' is thus generally understood to refer to the brown powder into which these ...

extraction of titanium - chemguide

Titanium can't be extracted by reducing the ore using carbon as a cheap reducing agent. The problem is that titanium forms a carbide, TiC, if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle. That means that you have to use an alternative reducing agent.
