Economic Geology of Niobium and Tantalum

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.
