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 Tantalum

Refining Tantalum. Pure tantalum is not found naturally. Tantalum i. s obtained commercially by first creating tantalum oxide (TaO 5). The tin industry also produces tantalum as a by product from smelting cassiterite ore concentrates for processing.

Resilience in the tantalum supply chain ScienceDirect

Feb 01, 2018 Tantalum scrap generated during the production of intermediate products has a high purity and is easy to collect and re-melt directly, and therefore gets fully recycled. Pre-consumer recycling plays a special role in the tantalum system. Well-established methods of pre-consumer recycling and recycled tantalum receive the conflict-free status.

Refining of tantalum by sacrificial and carbon deoxidation

Feb 01, 1984 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.

Tantalum Wikipedia

Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum
