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 processing History, Ores, Mining, & Extraction

Ores. Niobium occurs mostly as an oxide and has a strong geochemical coherence with tantalum. Major minerals of niobium are pyrochlore [(Na, Ca) 2 Nb 2 O 6 F] and columbite [(Fe, Mn)(Nb, Ta) 2 O 6], consisting of niobate, tantalate, iron, and manganese.Pyrochlore occurs usually in carbonatites and in pegmatite derived from alkalic rocks, commonly in association with zirconium, titanium
