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. Get price

Separation and Concentration

6. Separation and concentration. Following milling, the ore is subjected to different processes according to its nature. Pulp may require to be thickened ahead of these processes in large tanks called Thickeners, in which the solid component is allowed to settle and is raked towards the centre by large, rotating rakes while relatively clear water overflows into a peripheral drain or Launder.

Tantalum Processing

Tantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a molten salt system at high temperature. The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride. Get price

niobium processing

The tantalum-rich ore or ferroalloy is then crushed, ground, and decomposed in hydrofluoric acid. This is followed by a liquid-liquid extraction process, in which the two metals are dissolved in a slightly acidic aqueous feed solution into which an organic solvent, usually methyl isobutyl ketone, is mixed.
