  • niobium processing History Ores Mining Extraction

    The tantalum is extracted as a fluoride in the organic solution while niobium remains in the aqueous residue or raffinate. The niobium is then precipitated from solution as a fluoride by the addition of ammonium hydroxide and the filter cake is dried and roasted or calcined at 900–1 000 °C (1 650–1 800 °F) to obtain niobium pentoxide.
