PDF Assessment Of Beneficiation Routes Of Tantalite Ores

Tantalite is the most important mineral form of tantalum a specialty metal used mainly in the electronics industry for the manufacture of capacitors and in several specialty alloy appli ions. The beneficiation of tantalite ores usually involves pre concentration primary concentration and concentrate clean up.

Beneficiation and Separation of Egyptian Tantalite Ore

Abstract: Beneficiation of a lowgrade titanomagnetite ore containing 18.52Fe and 6.65TiO2 was conducted by dry and wet low intensity magnetic separators. Effects of different variables such as magnetic intensity grinding fineness and stages of separation were investigated in details. The ore was firstly preconcentrated by a dry low

a tantalite ore in which the tantalum content is three times more the novel flowsheet was more effective for columbitetantalite beneficiation and beneficial to the comprehensive recovery of

Assessment Of Beneficiation Routes Of Tantalite Ores From Key

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 wellknown lo ions of the mineral in the country were analyzed with 109Cd excitation source Energy Dispersive Xray spectrometry using

Alternative beneficiation of tantalite and removal of

The beneficiation methods for Ethiopian Kenticha pegmatitespodumene ores were assessed through mineralogical and quantitative analyses with Xray diffraction XRD and energydispersive Xray fluorescence EDXRF . The tantalite in the upper zone of the Kenticha pegmatitespodumene deposit is 58.7wt higher than that in the inner zone. XRD analysis revealed that the upper zone is dominated

Alternative beneficiation of tantalite and removal of

Repeated cleaning and beneficiation of the upperzone ore resulted in concentrate compositions of 57.34wt of Ta 2 O 5 and 5.41wt of Nb 2 O 5 . Washing the tantalite concentrates using 1vol KOH and 1 M H 2 SO 4 led to the removal of thorium and uranium radioactive oxides from the concentrate.
