    • DFT modelling of tantalum pentafluoride extraction with phosphorus-based extractants – a molecular dynamics study 

      Ungerer, M.J.; Van Sittert, C.G.C.E.; Van der Westhuizen, D.J.; Krieg, H.M. (Elsevier, 2019)
      Solvent extraction (SX) is a powerful method for both the separation and extraction of metals, resulting in high purity metals. The transition metals tantalum (Ta) and niobium (Nb) are of considerable significance, for ...
    • The time dependent solvent extraction of Ta and Nb 

      Van der Westhuizen, Derik J.; De Beer, Leon; Ungerer, Marietjie J.; Krieg, Henning M. (Trans Tech Publications, 2014)
      The suitability of Liquid-liquid extraction (LLE) for the selective extraction of chemically similar tantalum (Ta) and niobium (Nb) mixtures was investigated by determining the influence of the acid concentration, extractant ...
