2019520&ensp·&enspThe 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. However tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2). [2]

Tantalite The mineral columbitetantalite information

The Mineral tantalite 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.

Such pegmatites are widely exposed in Sec. 22 T.39N. R.17E (Kohler 1988 1989). Columbitetantalite is also found as crystals up to 2 cm long in a pegmatite in the NE SW SE Sec. 29 T.39N R.17E (Koehler 1989 personal communication). Some of this material has been shown to be manganocolumbite and manganotantalite (Falster et al. 1995).
