ICP-OES Determination of Ta, Nb, Fe, Ti, Sn, Mn, and W in Indian

Indian tantalite-niobate ore concentrate is analyzed for Ta, Nb, Fe, Ti, Sn, Mn, and W con-tent using ICP-OES. This paper evaluates two different methods of dissolution of the concentrated ore, namely microwave digestion and fusion. For microwave diges-tion of the ore samples, a mix-ture of acids (HBF 4, HCl, HF, etc.) was used for complete dissolu-tion.

Alternative beneficiation of tantalite and removal of radioactive

2019. 10. 16.· concentrating tantalite ore are gravity and magnetic separa-tions. Secondary ore concentration stages are generally re-quired to increase the content of Ta2O5 before further processing to recover Ta and Nb and to remove associated Ta-bearing minerals, impurities, and radioactive elements to acceptable levels [1–2,18].

Separation and Concentration Mineral Processing

Gravity Separation is used to separate mineral and gangue with a large difference in their Specific Gravities. Chromite, tin, tantalite and various heavy metals are amenable to this principle. Some gold ores contain Free Gold which can be recovered by gravity separation and this is the traditional method used in artisanal gold mining.
