Hydrometallurgical Process for Tantalum Recovery from Epoxy

14/04/2019Additionally, tantalum ore always contains a considerable amount of niobium, and a lot of energy is required to remove niobium during the tantalum refining process . The problem is that niobium and tantalum have similar chemical characteristics, which makes refinement difficult. However, the tantalum used in capacitors is free of niobium. Hence

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.
