SOLVOMET/SIM2 researchers have demonstrated in the journal Green Chemistry that choline chloride-ethylene glycol based deep-eutectic solvents (DESs) are not stable during high-temperature leaching processes for cobalt recovery.

During 4 days, young students and researchers from 9 different institutions gathered in Sweden to visit mines, smelters, R&D centers and industrial plants. Here is the report of Carlos Quintero (SOLVOMET/SIM² KU Leuven).

On June 8, 2022, Panagiotis Xanthopoulos (SOLVOMET/SIM2 & MSCA-ETN SULTAN) obtained his PhD degree in Chemistry. He successfully defended his PhD thesis “Recovery of metal ions from dilute aqueous solutions by ion flotation”.

Within the framework of the EU Horizon 2020 project NEMO, SOLVOMET/SIM2 researchers have compared the effect of mixer-settlers and agitated columns on the separation of cobalt and nickel with Cyanex 272.

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.

To remine or not to remine extractive waste in Europe? That was the core question during the symposium "(Re)Mining Extractive Waste, A new business?" (Mechelen, May 17-18, 2022). SIM² Director Peter Tom Jones summarises the main lessons learned.

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.

Can mining waste become a raw material for (circular) construction materials? In this new video, the EU MSCA-ETN SULTAN team highlights the project results in terms of remining present day and historical sulphidic tailings.
