Not rare at all.

Titanium is abundant in the earth's crust and is extracted commercially from 
the ore minerals rutile (titanium dioxide) and ilmenite (iron-titanium 
oxide). The commercial extraction process involves treatment of the ore with 
chlorine gas to produce titanium tetrachloride, which is purified and reduced 
to a metallic titanium sponge by reaction with magnesium or sodium. The 
sponge, blended with alloying elements (and reclaimed scrap) as desired, is 
then vacuum melted. Several meltings may be necessary to achieve a 
homogeneous ingot which is ready for processing into useful shapes, typically 
by forging followed by rolling. For many applications the cost of titanium 
alloys can be justified on the basis of desirable properties.
