EXTRACTION AND SEPARATION OF TANTALUM AND NIOBIUM .

The principal minerals of niobium (Nb) and tantalum (Ta) are columbite and tantalite. This, depending on whether the concentration of niobium or tantalum is greater corresponds to the general formula (Fe,Mn)(Nb,Ta) 2O 6 (Damodaran et al.,1969). Tantalite ore is found primarily in Australia, Canada, Brazil, Southern Africa, Nigeria and

Tantalum

the chemically similar niobium, occurs in the minerals tantalite, columbite and coltan (a mix of columbite and tantalite). Tantalum is a rare metal, comprising just 8×10−9% of the universe, making it fifteen times less abundant in the universe than gold (which makes up 6×10−8%). Tantalum also comprises just ×10−4% of the earth's crust,

EUXENITE (Rare Earth Yttrium Niobium Tantalum Titanium Oxide)

Euxenite is found in rare earth rich, granite pegmatites, a slow cooling igneous intrusive rock. Euxenite is associated with quartz, feldspars, columbite, tantalite, monazite and other rare earth minerals. Euxenite is used as an ore for its rare earth metals and uranium.
