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