Solvent Extraction

Obtaining metals from aqueous solutions is a technological challenge due to the difficulty of separating these metals from each other and in relation to other metals present in industrial leach liquors. In this context, this line of research evaluates purification routes for these liquors using simple and synergistic solvent extraction. With this, it is possible to eliminate precipitation stages allowing obtaining concentrated and purified liquors that can be sent to the electrodeposition.

The phenomenon of synergy between extractants is also studied, using FT-IR (Infrared by Fourier Transform) techniques to support the proposal of mechanisms that describe the separation of metals. This approach differs totally from the works found in the literature. In addition, the formation of international human resources in hydrometallurgy is envisaged via the network between USP-UFMG-CDTN and USP-UFRGS, which can be expanded to other institutions in the mining-metallurgical sector.
