process of mining columbite

Columbite concentrates and tin slags with a high tantalum content (greater than 10 percent) are directly dressed in most cases by a wet chemical process.Low-tantalum tin slags, on the other hand, are first melted in an electric-arc furnace with the addition of a flux material, and the tantalum-niobium content is collected as a ferroalloy .

    The slurry is filtered and further processed bysolvent extraction. Using methyl isobutyl ketone (MIBK), or liquid ion exchange using an amine extractant in keroses, produces highly purified solutions of tantalum and niobium. Finally, this tantalum oxide is reduced with molten sodium to produce tantalum metal.

    Tantalum Processing | TIC

    Theextraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes thetantalum and niobium valuesto dissolve as complex fluorides, and numerous impurities that were present also dissolve.
