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.
