tantalum processing infomation

The extraction and refining of tantalum including the separation from niobium in these various tantalumcontaining mineral concentrates is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures This causes the tantalum and niobium values to dissolve as complex fluorides and numerous impurities that were present also dissolve
