  • Coltan - Wikipedia

    Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which are extracted the elements niobium and tantalum.The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture tantalum capacitors which are ...

  • Tantalite - Wikipedia

    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 (8.0+ compared to columbite's 5.2).
