How Tantalum Is Mined Sciencing

24/04/2017  The tantalum concentrate is transported to the processor for chemical processing. The concentrate is then treated with a mixture of hydrofluoric and sulphuric acids at high temperatures. This causes the tantalum and niobium to dissolve as fluorides. Numerous impurities are also dissolved.
