Marketable products of tantalite contain 25–35 % of tantalum oxide (Ta 2 O 5) (Shikika. 2020). The production of tantalum metals or chemicals starts with the conversion of Ta concentrates to an intermediate chemical such as Ta 2 O 5 or K 2 TaF 7 using, for instance, a mixture of H 2 SO 4 and HF, or a mixture of HCl and NaF (EC, 2017).
