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 ...

Kanyika Niobium Project — Globe Metals Mining

At the processing plant, ore is crushed and then ground to less than 0.1mm for treatment to recover pyrochlore – a mineral containing niobium and tantalum. Through a series of simple magnetic separation and flotation stages, a pyrochlore mineral concentrate is produced grading about 40% niobium and 1% tantalum. This concentrate is filtered and packed for export.
