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.

Refining of tantalum and tantalum scrap with carbon

1999-2-17  Tantalum refining can be defined as a process of impurity removal during metal consolidation by different sintering and melting techniques. Oxygen has been considered as a major interstitial impurity in refractory metals, and the most traditional technique used to reduce its content has been deoxidization of refractory metal oxide within the metal (e.g. tantalum pentoxide) with carbon.

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.
