| Abstract Scope |
Environmental and economic feasibility of extraction/separation of niobium-tantalum metallic ions from their minerals have to an extent, created major concerns. The simplicity, wide scope and rapid nature of solvent extraction process have made it mostly favored and commonly adopted as a metal-ion separation method in separating these metals from their mineral complexes. However, this technique often adopts difficult, tedious and complex procedures. Solvent extraction and membrane separation often employ certain solvents regarded harmful/toxic to humans and the environment. Hence, advancements to the conventional solvent extraction have been exploited. Advances/developments in these separation technologies such as the incorporation of membrane separations (liquid membrane transport) as a continuous system have displayed positive establishment with employment of green designer solvents (ionic liquids) as alternative routes. Thus, this study will provide more insights into recent advancements of Nb/Ta separation, identification and understanding such separation application mechanism as well as comparative recommendations for future trend. |
