About This Course

Mixing and separating for recycling and reformulation of metals as well as electrolytes contained in extremis « wastes » requires to master dissolution, formulation of complex fluid, selective extraction and finally re-mixing in order to obtain recycled product with new economic value. These lectures focus on the scientific basis of recycling and delivery, illustrated by knowledge-based examples of optimized technology involved in effective separation of species between phases.

This 25 lectures are organized in three chapters:

1. Pre-requisite knowledge (optionnal):

Solvents and solubilisation - Deep eutectic solvents - Chemical potential: a general view at equilibrium - The Gibbs triangle and its usage - Osmosis and electrolyte solutions - Specific ion effects in solution - Specific ion effects at interfaces - Dynamics in electrolytes solution: a panorama

2. Scientific basis of mixing and separating:

Establishing binary phase diagram - Pseudo-phases versus microphases - Reading binary phase diagrams - Solubilisation in two phases systems - Establishing ternary phase diagrams - Ternary phase diagrams (prism and its cuts) - Ternary phase diagrams (curvatures) - Contacting two liquids for extraction - Basis of liquid-liquid extraction: chemistry and molecular forces - Mass balance , fluxes and yield in distillation and extraction

3. Implementation in efficient separation processes

Basic concepts of liquid formulation - Liquid–liquid extraction at meso-scale - Liquid-liquid extraction at macroscale - Cloud point extraction in practice - Ionic liquids - Ternary phase diagrams and safety of extraction - Separation by transport properties : flottation- Hydrotropes and surfactant-free microemulsions -

You will have the access to the lectures of the first Chapter from the beginning . The lectures of the other chapters will be delivered on a weekly basis.

Une réussite aux Quizz proposés à l’issue du cours donnera accès à l’inscription à des travaux pratiques, organisés à l’université de Montpellier, mettant en œuvre les concepts étudiés.


Bachelor level in physicochemistry


Professor Thomas Zemb is full Professor at INTSN and Mercator Professor at TU Berlin. He was teaching nuclear separation chemistry and colloidal physical chemistry at UPMC till 1999. Co-founder of the European masters COSOM at University Regensburg, teaching physical chemistry of perfumes and aroma at University of Versailles. His research and teaching activities at University of Montpellier activities, as founding Director of the Institute for separation chemistry of Marcoule are linked to separation, extraction and recycling chemistry since then./staff member #1


Professor Werner Kunz is holder of the chair of physical and theoretical chemistry (“Solution Chemistry”) at Regensburg University. The characterization, conception and practical application of complex and nano-structured liquids and their interfaces define the central research interests of Prof. W.Kunz/staff member #2


Jean-François Dufrêche studied physical chemistry at the Ecole Normale Supérieure de Lyon and received his Ph.D. degree from University UMPC-Paris 6 (direction of Prof. P. Turq). After a postdoctoral stay in Cambridge (UK) with Prof. J.-P. Hansen, he joined CNRS in 2003 where he studied electrolyte solutions. Since 2001, he has been a Professor at the University of Montpellier in the Institute for Separation Chemistry in Marcoule. His research interests are focused on multi-scale modelling, with applications to separation processes, such as liquid extraction/staff member #3
