The mineral group tantalite [ (Fe, Mn) Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal. 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.

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 …

Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.

Tantalite, tantalum-rich variety of the mineral columbite (q.v.) with the chemical formula (Fe,Mn) (Ta,Nb)2O6. Tantalite is the principal ore of the metal.

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is tantalite. [1]

From ferrous iron content and the Greek mythological Tantalus, for the difficulty of dissolving the mineral. The original material with Fe>Mn was called Tantalite, subsequent name changes recognized the compositional variability of the series.
