Srdjan M. Bulatovic, in Handbook of Flotation Reagents: Chemistry, Theory and Practice, 2010. 22.1 Introduction. Niobium minerals, especially columbite, are also associated with other valuable minerals, such as tantalum, zircon and rare earth minerals. Pyrochlore and a mixture of pyrochlore and columbite have different origins, and therefore, beneficiation of pyrochlore and columbite are

Blue River Tantalum and Niobium Pro Commerce Resources

Metallurgical testwork shows that the ferrocolumbite and pyrochlore which host the tantalum and niobium mineralization are amenable to a two-stage process of conventional flotation and proven refining processes with estimated recoveries of 65% to 70%. The first step of the process uses grinding followed by flotation to produce a concentrate.

Tantalum and Niobium Mining SGS

Tantalum and niobium processing can be difficult because the minerals are brittle, heavy and typically highly intergrown with sulfide and other oxide minerals. SGS has contributed to many tantalum projects over the years and can bring an integrated suite of services to tantalum and niobium exploration or development projects.

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
