MINERAL PROCESSING AND RECOVERY OF TANTALUM

Concentrates of Golpejas and Penouta contain columbo tantalite. Up to 15 of the total tantalum and niobium content of these concentrates are present in the cassiterite as microinclusions and can not be recovered by the mineral processing. These elements are concentrated in the tin slag during the metallurgical processing of cassiterite.

Selective recovery of niobium and tantalum from low

 · This value corresponds to a recovery yield of 65 for Ta. This means that Ta behaves like Nb throughout the process. This result was expected given the almost identical chemical properties that exhibit Nb(V) and Ta(V). Therefore the process described in the present study allows the recovery of both Nb and Ta from low-grade concentrates.

Assessment Of Beneficiation Routes Of Tantalite Ores From

The beneficiation methods for some tantalite ores from selected deposits in Nigeria have been assessed through mineralogical and compositional analyses of the ores. Tantalite ores obtained from eight different well-known locations of the mineral in the country were analyzed with 109Cd excitation source Energy Dispersive X-ray spectrometry using the emission-transmission method of quantification.
