IJMMME - Mineralogical Characterisation of

Most of tantalum-bearing minerals of the Bolivian placers belong to the columbite group minerals, whereas in Penouta, microlite is more abundant. Columbite usually exhibit a concentric zoning, whin a Nb-rich core and a Ta-rich rim. Keywords: Tantalum, Ore processing, Milling, Mineralogical characterization, tantalite, Microlite
