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 ...

Niobium Ore - an overview ScienceDirect Topics

In the richest niobium ores known in the world, the Nb 2 O 5 content may reach up to 1% to 4%. The leading mineral resources of niobium at the moment are in Brazil (84.2% of total), Canada (9.8%), and Zaire (4.2%). The primary Brazilian ore is the pyrochlore type, which is easier to enrich than the columbite/tantalite ores (Gupta et al., 1994).
