Tantalite: Mineral information, data and localities.

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.

How Tantalum Is Found

It is found in tantalum-bearing oxide minerals such as euxenite, microlite, polycrase, tantalite, columbite and wodginite. Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0. 01 to 1 percent tantalum pentoxide, which is equivalent to 0. 1 to 10 kilograms per metric ton.
