SOLVOMET/SIM² researchers have published their research on the effect of polar organic solvents on the solvent extraction process for rare-earth separation. The research was performed in the framework of the H2020 project NEMO.

On March 10, 2022, the joint NEMO/CROCODILE/TARANTULA expert panel discussed the “Global perspectives on the reprocessing of mine tailings”. The objective was to find common ground and to enable the elaboration of specific EU policy recommendations.

SOLVOMET/SIM² researchers have published their research on a solvometallurgical process for the recovery of cobalt from lithium-ion batteries in Green Chemistry. The research was performed within the framework of the Horizon 2020 project CROCODILE.

Within the context of EU NEMO, SIM² KU Leuven/SOLVOMET researchers developed a non-aqueous solvent extraction process for the separation of heavy rare earths (HREEs). The work was published in Separation & Purification Technology.

SOLVOMET/SIM² researchers have published a critical review paper in Industrial & Engineering Chemistry Research on the different systems and mechanisms of non-aqueous solvent extraction, providing a framework for future processes.

In the framework of the International Conference on Raw Materials and Circular Economy #RawMat2021, held on September, 5-9th 2021 in Athens (Greece), Lourdes Yurramendi presented the Oral Communication: A sustainable process for the recovery of valuable metals from spent lithium ion batteries by deep eutectic solvents leaching (L. Yurramendi, J. Hidalgo, A. Siriwardana) With this work, Dr. Lourdes Yurramendi represented ...

SULTAN, the EU Training Network for the remediation and reprocessing of sulphidic mining waste sites, has launched its long-awaited Thematic Section in the Journal of Sustainable Metallurgy, comprising 10 research papers.

The France TV made a report on the work of our partner BRGM in the CROCODILE project: “In Orléans, a team of BRGM researchers has succeeded in extracting nickel and cobalt contained in New Caledonian mines using natural thermal bacteria. In a few years, this more ecological industrial process will be available.” The article is in French and you can ...

The 2-day symposium “(Re)Mining extractive waste, a new business?” gathers leading experts in the field of (re)mining of mining-related waste, with a focus on the tailings that arise during the mining and processing of sulphidic ores.

SINTEF has developed an innovative diaphragm lab-scale electrowinning flow cell that allows optimization and process developent under conditions closer to industrial environment. The cell has been used in WP3 to verify real Co sulfate solutions from spent Li ion batteries (produced by TECNALIA and KU LEUVEN), giving high purity Co metal and acceptable energy consumption.
