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, titaniumget price
MINING AND PROCESSING : Tantalum is produced by the processing and refining of its ore tantalite. Tantalite is the mineral ore containing tantalum. Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum.get price

Tantalum deposits in Europe have low ore concentrations and with the present methods of processing they are not economically viable their exploitation. The mineralogical characterization of the tantalum ore is necessary to determine the grade that could be provided during the ore processing.get price
In 2000, Australia produced around 45% of the world’s tantalum concentrates (tantalum-containing minerals), but by 2014 this dropped to just 4%. The substantial decrease was a result of high extraction and an unfavourable exchange rate, which meant that mining the ore was no longer viable in Australia.get price
