Tantalum Processing TIC

The extraction 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.

Refining of tantalum by sacrificial and carbon deoxidation ...

1984-2-1  The purification of the same charge by sacrificial deoxidation alone would involve a loss of 7% of the tantalum. The results are explained using available and estimated thermodynamic data for the Ta-C-O system. In view of the present observations, a modification incorporating carbon deoxidation in the refining flow sheet of tantalum is suggested.
