A Review of NiobiumTantalum Separation in Hydrometallurgy

Niobium and tantalum are chemically similar and are associated with each other in nature which makes it very difficult to separate. For many years, the separation of tantalum from niobium involved the fractional crystallization of potassium heptafluorotantalate away from potassium oxypentafluoroniobate monohydrate, this method has been supplanted by solvent extraction from fluoridecontaining

A Review of NiobiumTantalum Separation in Hydrometallurgy

Both niobium and tantalum extract at high concentration of H2SO4 (>8N), but only tantalum extracts at lower acidity (3N8N). Initially niobium and tantalum are extracted together in the organic phase (MIBK) at greater than 8N H2SO4. Under these conditions most of the impurities such as iron, manganese and magnesium remain in the aqueous phase.
