Tantalum-niobium ore is a general term for minerals containing tantalum and niobium. There are many important tantalum-niobium minerals with industrial value, mainly niobium iron ore, tantalite or pyrochlore. Some tantalum-niobium exists as impurities in ilmenite, perovskite, rutile, cassiterite, wolframite and titanite.
Tantalum has many diverse uses and so the supply chain that feeds these final products is complex. Mining for tantalum includes the beneficiation of the ore to a primary concentrate (4-7% Ta 2 O 5) or secondary concentrate (28% Ta 2 O 5). Refiners further improve the purity and produce pure tantalum in metal or powder form.
3.1. Beneficiation: the successful beneficiation of tantalite ore is greatly depending on the ore physi ochemical properties s uch as specific gravity difference and the response to a magnetic field .
The tantalum and niobium ore beneficiation and roughing generally adopt the gravity separation method, and the selection adopts the gravity separation, flotation, electromagnetic separation, or the combined process of beneficiation and smelting.To deal with the ore with a high content of powder or primary mud, the washing operation is essential. High …
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 …
