Related to tantalite: tantalum, columbite, coltan


A black to red-brown mineral, (Fe,Mn)(Ta,Nb)2O6, distinguished from columbite by the predominance of tantalum over niobium and used as an ore of both elements.

Due to the higher solubility of tantalite relative to that of columbite in peraluminous granitic magmas [3, 65], one can expect a late Ta enrichment relative to Nb in the residual melt and thus a high Ta/Nb ratio in the exsolved magmatic fluid, despite low partition coefficients for Nb and Ta between an aqueous fluid and silicate melt in granitic systems ([D.sup.fluid-melt] [Ta] < [D.sup.fluid-melt] [Nb] < 0.1) [3, 66-68].
