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.

Improved solvent extraction recovery of tantalum and niobium oxides from an acid solution of raw materials containing such oxides wherein the charged organic solvent [e.g., MIBK] is washed out (a) with 8-16N sulfuric acid and then (b) with water or dilute HF. This avoids the use of a second mineral acid addition after digestion by HF of raw materials (and avoids problems attendant to use a
