STUDY MINERAL COLUMBITE- TANTALITE WITH METALLURGICAL APPROACH TO DEFINE THE USE OF SAND DEPOSITS WITH HEAVY MINERALS
The aim of this work was to study a sample of sand from a site of Bolivia, in order to obtain a pre-concentrate high grade Nb-Ta. Particle size analysis was performed and quantified in each class the chemical composition of Nb and Ta. In addition, the sample was analyzed mineralogical. According to...

| Summary: | The aim of this work was to study a sample of sand from a site of Bolivia, in order to obtain a pre-concentrate high grade Nb-Ta. Particle size analysis was performed and quantified in each class the chemical composition of Nb and Ta. In addition, the sample was analyzed mineralogical. According to the physical properties of the mineral: paramagnetism and high specific gravity, two methodologies proposed concentration. The first was to conduct a magnetic separation on a sorted sample. In the second approach the gravity concentration and subsequent magnetic separation was used. Finally, the grade and recovery of Nb and Ta raised the two methodologies were evaluated. It’s concluded that the gravity concentration followed by magnetic separation is the process for Nb-Ta preconcentrate. |
