  • Tantalum and niobium Critical Metals Handbook Wiley

    27/12/2013· Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum minerals are oxides, rather than silicates, sulfides or phosphates. Three types of niobium and tantalum deposits are: carbonatite‐hosted deposits; alkaline to peralkaline granites and

  • A review on extractive metallurgy of tantalum and niobium

    To this end, the existing information on the hydrometallurgical methods for leaching of tantalum and niobium has been systematically collected and described, together with the extractive and purification processes that deliver Ta and Nb as oxides or as pure metals. Furthermore, the common operations belonging to the upstream processing of the colombo-tantalite, such as magnetic and gravimetric

    Tantalum was discovered in Sweden in 1802 by Anders Ekeberg. One year earlier, Charles Hatchett had discovered columbium (now niobium). In 1809 the English chemist William Hyde Wollaston compared its oxide, columbite with a density of 5.918 g/cm3, to that of tantalum, with a density of 7.935 g/cm3. He concluded that the two oxides, despite their difference in measured density, were identicalОнлайн-запрос

    The tantalum and niobium fluoride complexes are then removed from the aqueous solution by liquid-liquid extraction into organic solvents, such as cyclohexanone, octanol, and methyl isobutyl ketone. This simple procedure allows the removal of most metal-containing impurities (e.g. iron, manganese, titanium, zirconium), which remain in the aqueous phase in the form of their fluorides and other
