Nowadays titanium is manufactured by the Kroll process. First you heat titanium dioxide with carbon to about 1000 degrees C and pass chlorine over it. This makes TiCl4. People call that "Tickle". Then you cover the Tickle with an argon blanket and react with hot magnesium [at 850 degrees C] to get the metallic element.
