The project focuses on the elaboration of a physicochemical model for metal ion binding to humic nanoparticles (HNPs) with account of electrostatic contribution beyond the representation classically assumed in the common metal speciation codes NICA‐Donnan or WHAM. The model is based on the combination between (i) non‐linear Poisson‐Boltzmann Theory applied to Soft (ion‐permeable) particles like HNPs (SPBT), and (ii) Non‐Ideal Competitive Adsorption (NICA) complexation formalism to capture the very chemical component of the binding. The project is organized according to 3 steps: writing a new computational software combining NICA and SPBT; developing a fitting toolbox to retrieve metal/HNPs binding parameters from NICA‐SPBT ‐based analysis of metal‐HNPs titration data with help of a freely available software for the adjustment and estimation of relevant model parameters (PEST).

Geometallurgical assessment of unconventional Li and critical metals bearing deposits
The research activity on the geometallurgical assessment of Li-bearing rare metals granite ore deposit with reference to beneficiation processes will be related with the “Minerals engineering” team. The candidate will integrate an active and dynamic research group with two senior researcher and 2-3 PhD and Master students and will be involved in experimental research and academic tuition depending on candidate’s curricula. In addition, through this project, the candidate will also beneficiate the collaboration with the geometallurgy team of the Geological Survey of Finland (GTK) (Pr A.Butcher and Dr Q.Dehaine).

Kinetics of processes in terrestrial & extra-terrestrial igneous rocks
The project is focused on the kinetics of igneous processes in terrestrial and extra-terrestrial samples. By using diffusion chronometry the young researcher will tackle the kinetics of mush aggregation and disaggregation in continental rift settings (e.g., East-African Rift), and the kinetics of planetary body accretion by using specific chondrite samples. Other working sites will be welcomed. The project will partly rely on the access to two SIMS facilities at CRPG (CRPG SIMS are equipped with RF-source that allow small spot-size analysis, down to 2 µm), and will use, among others elements, Li as a tracer (element and stable isotope profiles) to quantify kinetics. We are looking for candidates with a record in diffusion chronometry. The funding is for 18 months (with possible extension) and will start as soon the position is filled.
