The most stable of these is 92 Nb with a half life of 34.7 million years. One of the least stable is 113 Nb, with an estimated half life of 30 milliseconds. Isotopes that are lighter than the stable 93 Nb tend to decay by β + decay, and those that are heavier tend to decay by β

The ore is refined using a variety of methods to obtain concentrates of approximately 70% 2 O 5 . This concentrate is then dissolved in a mixture of hydrofluoric and sulfuric acid. The resulting fluoride complex is then converted to an organic phase by means of a liquid extraction process. The organic phase is separated from the aqueous phase.
