niobium processing and refining equipment

Processing: extraction and refining

Processing: extraction and refining. Two separate processing schemes are utilized for niobium production. Those companies that mine pyrochlore convert the niobium oxide units into HSLA ferroniobium through the aluminothermic reduction process or by reduction in an electric arc furnace. CBMM has installed capacity for the production of a high

niobium processing

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.

Niobium alloys and high temperature applications

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 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

Electron BeamMelting and Refining Niobium

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

Niobium Extraction, RefiningProduction

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.
