About Tantalite Hide. Formula: (Mn,Fe) (Ta,Nb)2O6. An obsolete group name for minerals with the general formula (Mn,Fe) (Ta,Nb) 2 O 6, equivalent to the Tantalite- (Fe)-Tantalite- (Mn) Series. Generally mangan-dominant members are more abundant in nature. Many specimens called tantalite actually belong to the columbite series or tapiolite series.

The mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.However, tantalite has a much greater specific gravity than columbite (8.0+ …
