The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semisingular mineral called coltan or "columbitetantalite" in many mineral guides.
Tantalite forms a solid solution series with Columbite known as the ColumbiteTantalite series. Tantalite is the tantalumrich member, and Columbite is the niobiumrich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.
An obsolete group name for minerals with the general formula (Mn,Fe)(Ta,Nb) 2 O 6, equivalent to the Tantalite(Fe)Tantalite(Mn) mangandominant members are more abundant in nature. Many specimens called tantalite actually belong to the columbite series or tapiolite series. Visit for gemological information about Tantalite.
