Tantalum And Niobium

Jul 28, 2009· The extraction of niobium from other mineral concentrates and tin slags uses the same technology as that of tantalum, that is, digestion with hydrofluoric acid followed by liquid-liquid extraction with methyl isobutyl ketone (MIBK) Niobium oxide is precipitated from the niobium stream by ammonia and then purified and calcined.

A Review of Niobium-Tantalum 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 fluoride-containing.
