refining system for tantalum

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

1984-2-1  Modification of the refining flow sheet of tantalum Sodium-reduced tantalum powder is refined by electron beam melting during which all the oxygen in tantalum is eliminated as Ta0(g). The modification suggested here is to incorporate a calculated quantity of carbon in the tantalum powder before the pyrovacuum treatment.

Niobium Extraction, Refining Production TIC -

CBMM has installed capacity for the production of a high purity oxide that can be used to produce vacuum grade ferro- and nickel-niobium as well as niobium metal ingots via electron beam refining. The use of columbite and tantalum-bearing ores, such as tantalite, as feedstocks results in the necessity to process these materials chemically as described in the tantalum section.

Resilience in the tantalum supply chain - ScienceDirect

2018-2-1  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.
