columbite and tantalum ore beneficiation technologies

columbite and tantalite ore -

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%.
