Extraction of niobium and tantalum from ferrocolumbite by

Abstract Pressure acid leaching was used to extract niobium and tantalum from a ferrocolumbite ore. The leaching was carried out in a pressure reactor using hydrofluoric acid as leachant. Various parameters, such as temperature, reaction time, HF concentration, stirring speed, particle size and solid-to-liquid ratio in the leaching process, were optimized. The reactants and products were ...

Niobium and tantalum beneficiation using gasphase

Niobium and tantalum beneficiation using gasphase

Ore digestion in aqueous mixtures of sulfuric and hydrofluoric acid, followed by selective liquid-liquid extraction, is the method of choice for recovery of tantalum and niobium from the parent minerals. As this method has significant environmental and practical drawbacks, there is a need for a new process to beneficiate these minerals.

Oct 26, 2016 The beneficiation methods for Ethiopian Kenticha pegmatite-spodumene ores were assessed through mineralogical and quantitative analyses with X-ray diffraction XRD and energy-dispersive X-ray fluorescence EDXRF. The tantalite in the upper zone of the Kenticha pegmatite-spodumene deposit is 58.7wt higher than that in the inner zone. XRD analysis revealed that the

A Review of NiobiumTantalum Separation in

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 ...

niobium processing History Ores Mining amp Extraction

This is followed by a liquid-liquid extraction process, in which the two metals are dissolved in a slightly acidic aqueous feed solution into which an organic solvent, usually methyl isobutyl ketone, is mixed. The tantalum is extracted as a fluoride in the organic solution, while niobium remains in the aqueous residue, or raffinate.
