Who discovered niobium?

Niobium was the first of these two elements to be discovered. In 1801, Charles Hatchett (1765-1847), an English chemist, analysed a specimen of an unknown mineral from the collection of the British Museum in London.

Where is niobium found?

Niobium has no known biological role. The main source of this element is the mineral columbite. This mineral also contains tantalum and the two elements are mined together. Columbite is found in Canada, Brazil, Australia, Nigeria and elsewhere.
