Refining Tantalum

Tantalum i  s obtained commercially by first creating tantalum oxide (TaO5). The tin industry also produces tantalum as a by product from smelting cassiterite ore concentrates for processing. The biggest tantalum mine is the Mibra operation in Nazareno, Brazil. In the mine accounted for 510% global production.

aluminium oxide and ferroniobium, an alloy of iron and niobium used in the steel production [21, 22]. The ferroniobium contains between 60 and 70% of niobium [23]. Without addition of iron oxide, aluminothermic process is used for the production of niobium. Further purification is necessary to reach the grade for superconductive alloys.
