Titanium is a metal of modern times. It is obtained as oxide. Why it could not be extracted earlier despite its wide occurence?

Solution

Titanium is extracted from its ore, rutile - TiO₂. It is first converted into titanium(IV) chloride, which is then reduced to titanium using either magnesium or sodium. The ore rutile (impure titanium(IV) oxide) is heated with chlorine and coke at a temperature of about 1000°C.

It could not be extracted earlier because it was very difficult to get titanium of high purity required are special applications which is not known in earlier.
