Tantalite - Wikipedia The mineral group tantalite [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. Iron-rich tantalite is the mineral tantalite- or ferrotantalite and manganese-rich is tantalite- or manganotantalite. Tantalite is also very close to tapiolite.
