DFT modelling of tantalum pentafluoride extraction with phosphorus-based extractants – a molecular dynamics study
(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 ... -
Molecular modelling of tantalum fluoride in sulphuric acid medium: a DFT study
(Elsevier, 2019)During the solvent extraction (SX) experiments of tantalum (Ta) and niobium (Nb), the aqueous phase consisted of tantalum- and niobium penta-fluoride (Ta(Nb)F5), water (H2O) and sulphuric acid (H2SO4), which was contacted ... -
Molecular modelling of tantalum penta-halides during hydrolysis and oxidation reactions
(Elsevier, 2016)The transition metals tantalum (Ta) and niobium (Nb), which are usually found together in nature, have similar chemical and physical properties, making their separation challenging. There are various methods available for ...
