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.
The demand for tantalum and niobium has increased steadily due to their importance in the production of modern industrial materials and high tech consumer products such as super alloys and cell phones. This work aims at recovery of tantalum and niobium from Abu Dabbab deposits at the Eastern Desert of Egypt. The beneficiation was successfully performed using shaking table concentrator and.
Tantalum is produced as a byproduct by the tin industry from smelting cassiterite ore concentrates for processing. The biggest tantalum mine is the Mibra mine in Nazareno, Brazil. The Extraction and refining of tantalum is done by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures, because of which.
