The mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum. 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. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2). Iron-rich tantalite is the mineral tantalite-(Fe) or ferrotantalite and manganese-rich is tantalite-(Mn) or manganotantalite.

subsequently with the mining of Li and Be minerals. The early tin miners often overlooked the minerals of Nb and Ta or had a great difficulty in separating them from the tin. Consequently all cassiterite concentrates were contaminated with columbite-tantalite. Perhaps one of the best accounts on the occurrence of Nb and Ta minerals is that given by Frommurze et al.
