As I understand, Vanadium IS commonly found bound to other minerals, however. Can I ask you both to source your knowledge?

My source is the [url=http://en.wikipedia.org/wiki/Vanadium]wikipedia[/url] article, where it makes zero reference to vanadium found bound to iron in nature. Vanadium bound to iron is actually a high-strength alloy used to make high-durability steels where some of the higher-quality steel-alloys are not available/too expensive.
