"Hydrothermal mobility of Rare Earth Elements: solubility and partitioning by coupling experimental settings and geological observations"

The objectives: The project is looking to understand the mobility of Rare Earth Elements (REE) in hydrothermal conditions (100-300°C), with the objectives to constraint and decipher the key parameters finally leading to the formation of hydrothermal REE mineral deposits. More...Download (pdf)

"Predicting and understanding Rare Earth Element (REE) effects at the sediment-water interface"

Context: Effective and sustainable use of strategic mineral resources is a high societal, scientific and economical priority. Yet, information on the interactions between REE and biota is often limited, especially for sediment-dwelling organisms that may be the most impacted by such activities. In the absence of acid-mine drainage (More...Download (pdf)

"Geochemistry and mineralogy of scandium in laterites"

Laterites developed on ultrabasic rocks in New Caledonia contain exploitable concentration of Ni, as well as Co depending of the ore processing. Laterites may also contain scandium at low concentrations, but significantly enriched in comparison with the source rocks (protoliths), at a concentration  which could be of interest for a future exploitation.

"Ecological reclamation of Ni-mined Technosols" 

Mining operations for Ni recovery generate a high level of disturbances in the soils and the ecosystems, e.g. clearance of the endemic vegetation, removal of topsoils, loss of the biological fertility in the stocked topsoils, low fertility of the residual materials, increase in Cr VI toxicity More...

Postdoc position in GeoRessources Laboratory (Filled)"Flotation of fine-grained low grade oxides ores: physical chemistry and machinal modelling"

The research activity will be conduct within the “Mineral processing” team on fragmentation techniques and flotation of ores. Innovative research on the beneficiation of non-conventional and low-grade resources can be developed. Experiences on the process intensification by coupling with external fields (electric pulses, ultrasonic) will be an advantage More...Download (pdf)

"Role of hyperaccumulating plants in the biogeochemical cycle of nickel: distribution, chemical speciation and isotopic fingerprint"

BACKGROUND The role of vegetation in the cycle of metals, on their transformation and transfer at the Earth’s surface is widely assumed. Our knowledge about the mechanisms of soil-plant transfer is currently improved whilst unraveling the role of « sink » that plants can constitute for metallic contaminants. However, release mechanisms and fluxes towards environment are still rarely investigated. The contribution of litter to major and trace element fluxes is undeniable as this sink is able to provide the greater part of major and trace elements More...Download (pdf)
