Niobium and Tantalum Refining Process Equipment Niobium and tantalum do not occur naturally as free metals, but are essential components in a range of mineral species. The majority of these are oxide minerals; silicates of niobium and tantalum also substitute for major ions in a number of other minerals, in which they typically have low ...
Process variations. The high degree of flexibility of the EB heat source did lead to the development of several remelting and refining methods used from laboratory scale throughout to industrial production. Horizontal and vertical dripmelting. Both are the classical method for processing refractory metals such as Tantalum and Niobium.

Niobium oxide (Nb 2 O 5) is generally the starting chemical for the production of other compounds, such as niobium chloride (NbCl 5), niobium carbide (NbC), or lithium niobate (LiNbO 3). Niobium metal is produced by the aluminothermic reduction of the oxide followed by electron beam refining.
pyrochlore processing followed by the electron beam melting maybe applied on a muchlarger scale. In this process, the purity of niobium ingots does not depend directly on the purity of Nb205to be reduced because the electron beammelting has an excellent function for niobium purification. Therefore, the electron beam melting and refining ...

reduction and pyrovacuum refining. Depending on the purity desired, primary niobium is subjected to electron beam melt refining/electron beam floating zone refining to obtain the final product. Now one can see the path niobium ore travels before it becomes metal. It may be
The niobium (columbium until late 1970's) ore was at one point considered so crucial to the war (WWII) effort that it was reportedly flown into the country rather than risk loss at sea (4). For some time the extraction of niobium was dependent upon being a bi-product of tantalum refining. However, ultimately the process for obtaining high
Niobium processing, preparation of niobium ore for use in various products.. Niobium (Nb) has a body-centred cubic (bcc) crystal structure and a melting point of 2,468 °C (4,474 °F). Of the refractory metals, it has the lowest density and best workability; for this reason, niobium-based alloys are often used in aerospace applications.
