  • -Design and development of methodologies for the synthesis of molecular extractants. -Preparation of formo-phenolic type organic resin -Evaluation of the resins used in the extraction processes. -Study of extraction mechanisms. -Bibliographic search. -Dissemination and promotion of results through participation in conferences and the writing of reports, scientific articles and patents. -Participation in the collective tasks of the unit (advice, committee, seminars).

    He/she will participate in the research project within the framework of the ANR RECALL (Sustainable RECovery of vALuable metaLs in bauxite residue https: // anr.fr/Projet-ANR-20-CE04-0007). He/she will contribute to research activities in the field of chelating systems for separative chemistry (WP2 of the RECALL project) in the LTSM laboratory. He/she will primarily bring his/her expertise in the design, synthesis and characterization of new molecular architectures (functionalized phenolic precursors) for the preparation of specific organic resins and their implementation in hydrometallurgical processes for the extraction/separation of metals of interest in particular the rare earths present in the mining residues and more precisely the red mud (bauxite residues).

    -------- The main mission of the LTSM (UMR5257 – Marcoule site: https: // www. icsm.fr/index.php?pagendx=app140) is to carry out fundamental research based on the understanding the phenomena that influence ionic separation. Research work is thus directed towards the field of the synthesis of specific ligands and materials for the separation of ions, implemented in conventional extraction processes (liquid/liquid, solid/liquid) or unconventional (membranes, ionic liquids) with an orientation in understanding the mechanisms that govern the separation. Beyond the purely nuclear field, these selective effects are studied and implemented in various processes related to the recycling of materials associated with the production of energy and more generally, with a view to sustainable development, for example in decontamination or for the selective recycling of strategic metals.

    In the context of a circular economy, the RECALL project (Sustainable RECovery of vALuable metaLs in bauxite residue) aims to extract valuable metals from an industrial waste with the overall goal of reducing the pressure on natural mineral resources and scrutinizing all consequences in terms of human well-being In this context, the interdisciplinary and intersectoral RECALL project aims to develop sustainable processes (in aqueous media at relatively low temperature and without the use of solvents and strong mineral acids) to recover iron and critical metals (rare earth elements, gallium and scandium) from industrial waste and to value the economic impact of this technological change in terms of social welfare in which potential environmental and health impacts are taken into account.

    Eligibility criteria

    - Reactions and mechanisms of organic synthesis. - Multi-step synthesis methodologies. - Molecular characterization tools (UV, IR, multi-nucleus NMR, mass spectrometry). -Preparation and characterization of materials and organic resins (solid state NMR, FTIR, elemental analysis, electron microscopy) -General knowledge of coordination chemistry. -General knowledge of hydrometallurgy processes (solid-liquid separation) and associated characterization techniques (ICP, X-ray fluorescence).

    - Computer tools for collecting and processing data. - Oral and written presentation. - Oral and written comprehension of English level 2.
