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 semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than columbite …

Columbite-tantalite is the only primary niobium tantalum oxide mineral; its composition is dominated by Nb, Ta, Fe, and Mn. Ti is present in minor quantities (≤0.1 atoms per formula unit). In both plutons, the Ta/(Ta + Nb) and Mn/(Mn + Fe) of columbite-tantalite correlate positively with the degree of pegmatite evolution.
