Tantalum mining technique –blasting, crushing

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.

niobium processing History, Ores, Mining, & Extraction

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.
