Hydrometallurgy in Extraction Processes
Of these, the important ones are niobite-tantalite as pegmatites, pyrochlore as
carbonatites, and niobium-tantalum-bearing cassiterite as placer deposits.
Niobite-tantalite represents an iso- morphous series of niobates and tantalates of
iron ...

With soda, niobous anhydride fuses to a turbid mass, from which water dissolves
the excess of soda; after the removal of the latter, the niobite of sodium dissolves
in water. Fusion with carbonate of sodium has the same effect as fusion with ...

Extraction : The main source for niobium or tantalum is the mineral niobite. Since
the extraction for both the metals are similar, these two metals are extracted
together, freed from other elements and then separated from each other.

Despite the furnished interpretation, such a system (solid solution of uraninite
and niobite-tantalite) should theoretically not be excluded and should perhaps be
investigated further. As in the case of columbite replaced by uraninite, which in ...

Although the ratio of Nb to Ta in niobite concentrate is typically 10: 1, the Nb is
often regarded as a byproduct of Ta production. The main use for niobium is as
an alloying element in steel production, and for this purpose, niobite, pyrochlore,
...
A variety of Nb-bearing minerals were evolved in the early stage, precipitating as
niobite in large amounts and as ilmenorutile to a lesser extent, accompanied by
purochlore, nioboeschynite and fersmite. In the late stage, Nb occurred in fewer ...
