Effects of mechanical activation on the structural changes …

Estimates indicate that the amount of iron ore tailings generated and stockpiled on site (together with the existing tailings) within the KMA using the common beneficiation methods may reach 21–24 billion tons over the next fifty years. Tailings from beneficiation process containing up to 80–95% free silica pose potential risk of silicosis.

Primary beneficiation of tantalite using magnetic …

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 majority of iron and titanium, whereas H2SO4 leaching removed a large portion of …

Beneficiation and Separation of Egyptian Tantalite Ore

The beneficiation was successfully performed using shaking table concentrator and carpco magnetic separator. The enrichment ratio reached up to 160-times for both Ta 2 O 5 and Nb 2 O 5. Aliquat 336 ionic liquid was used for separating Ta 2 O 5 with purity of 90%. Amberlite anion exchanger was used for separating Nb 2 O 5 with purity of 87%.

Alternative beneficiation of tantalite and removal of …

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. …
