Oct 11, 2012 · ColumbiteTantalite is often found in lithiumand phosphaterich pegmatites and associated with such minerals as spodumene, beryl and lepidolite. Mining of these minerals is ongoing as tantalum is used in the manufacture of electronic capacitors. Niobium has uses in strengthening iron alloys, and in superconducting medical magnets.
