Zaraisky et al. (2010) determined the solubility of Ta 2 O 5 and Ta-bearing columbite in F− -, Cl − -, HCO 3− -, and CO 32 − -bearing solutions at 300–550 °C. The presence of F − increased the solubility of both phases by several orders of magnitude, indicating formation of F- or OH–F-bearing aqueous complexes.

· The columbite group is a solid solution with varying proportions of Nb or Ta in its composition. According to the International Mineralogical Association (IMA), ‘tantalite’ or ‘coltan’ are not scientific names, yet they are widely used. Many specimens commonly named tantalite are actually minerals of the columbite or tapiolite group

· Ta was found to be present predominantly in the solid-solution columbite-group mineral, along with minor Ta present as microlite and as impurities within cassiterite. It was found that over 70% of the Ta is contained within the −125 μm fraction, with the Ta-bearing minerals tantalite and microlite being closely associated with quartz.
