The mineralogical characteristics of tantalum–niobium ores from Songzi were investigated using mineral liberation analyzer (MLA) and chemical analysis. In particular, the chemical composition, phase composition, particle size, and dissemination characteristics of the ores were studied in detail. Results show that Ta2O5 and Nb2O5 have grades of …

The mineral is heavy, inherently paramagnetic, and is commonly associated with lighter gangue materials (primarily silicates). Generally, the beneficiation of columbite-tantalite involves gravity concentration units and additional magnetic and gravity separation steps to upgrade the concentrate [6,7].

The physical methods involved in the colombo-tantalite beneficiation (gravimetric and magnetic separation) allow to concentrate the colombo-tantalite fraction from the other accompanying minerals (Gerôme and Gérôme and Charlier, 2017 ).

Primary beneficiation of tantalite using magnetic separation and acid leaching. Primary beneficiation was successfully performed prior to dissolution of manganotantalite (sample A) and ferrotantalite (sample C) samples obtained from two different mines in the Naquissupa area, Mozambique. Magnetic separation removed the …

Carvalho et al. (2021) investigated the risks of human exposure to radiation associated with tantalite mining in Ethiopia and confirmed that there were risks associated with the high concentration ...

Processing of tantalite ore is started by ore milling to obtain good liberation of tantalum minerals, and then subjected to a series of physical processes involving gravity separation techniques.

The beneficiation methods for some tantalite ores from selected deposits in Nigeria have been assessed through mineralogical and compositional analyses of the ores.

The mineral is heavy, inherently paramagnetic, and is commonly associated with lighter gangue materials (primarily silicates). Generally, the beneficiation of columbite-tantalite involves gravity concentration units and additional magnetic and gravity separation steps to upgrade the concentrate [ 6, 7 ].

The beneficiation methods for some tantalite ores from selected deposits in Nigeria have been assessed through mineralogical and compositional analyses of the ores.

Compared with the conventional flowsheet, the novel flowsheet was more effective for columbite–tantalite beneficiation and beneficial to the comprehensive recovery of nonmetallic minerals.

Beneficiation is a variety of processes where by extracted ore from mining is separated into mineral and gangue through mechanical means, the former suitable for further processing or direct use. Through beneficiation technology low grade tantalite ore of 15% concentration can be increased to high grade tantalite ore of 50% or more …

The present review focuses on the effective beneficiation of columbite-tantalite, extraction and purification of Ta and Nb using various technologies and the feasibility of processes by considering present industrial practices and recent research.

The beneficiation methods for some tantalite ores from selected deposits in Nigeria have been assessed through mineralogical and compositional analyses of the ores.

The findings of this study suggest that the beneficiation and alkaline washing of Kenticha pegmatite–spodumene ores produce a high-grade export-quality tantalite concentrate with negligible radioactive oxides.

Mineral beneficiation processes to separate and purify different metals from complex mineral matrices such as tantalite, are normally dictated by elemental composition, physical and chemical properties of the impurities as well as those of the target analyte(s) [7].

The demand was spurred by cellphone manufacturing clients who needed the product. "We saw numerous tantalite mining bases being set up in Buhera and at the time tantalite was going for US$1 200 per kilogram. Today, the same product has drastically gone down to US$100 for the same weight. "Given the production costs and …

The present review focuses on the effective beneficiation of columbite-tantalite, extraction and purification of Ta and Nb using various technologies and the …

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 …

In this study, we determined the optimum conditions for the primary beneficiation (Fe removal with magnetic sepa-ration and radioactive material removal using acid leaching) of Mozambique tantalite sample ores with minimum losses of Ta and Nb prior to complete dissolution of the mineral ore.

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 …

The final step in this study was to investigate the possible beneficiation of the tantalite ore by combining the acid leaching with the magnetic removal and microwave dissolution of the mineral.

The dense medium beneficiation method is used for ores with a particle size of −10 mm + 0.5 mm. The dense medium cyclone is used as the dense medium sorting equipment; tantalite, columbite, or ferrotapiolite suspension is selected as the dense medium; the processing capacity of the dense medium cyclone can reach 50~100 tons …
