EXTRACTION AND REFINING : Pure tantalum is not found naturally. Tantalum is commercially obtained by first creating tantalum oxide (TaO 5). Tantalum is produced as a byproduct by the tin industry from smelting cassiterite ore concentrates for processing. The biggest tantalum mine is the Mibra mine in Nazareno, Brazil.

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.
Get QuoteThe steps that constitute the process are : leaching with sulphuric acid and nitric acid, removal of impurities, precipitation of palladium yellow salt (dichlorediamine-palladium(II)), reduction of this salt to metallic palladium and finally the smelting of this metal.
