  • Niobium Price 2019 [Updated Daily] - Metalary

    In 1846, Heinrich Rose, a German chemist, discovered that ores of tantalum contained another element, niobium. By 1865, scientists discovered that columbium and niobium were one and the same, as well as distinct from tantalum. For the next century, columbium and niobium were interchangeably used.

  • 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 tantalite.

    Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.
