Deep eutectic solvents (DESs) are considered as a cheap alternative to ionic liquids, and in the last years they have been used in a broad range of applications, including extractive metallurgy. Some of the most extensively used DESs are a combination of carboxylic...
Recently, the EC’s Joint Research Centre (in Ispra) has published a milestone report on the recovery of cricial (and other) raw materials (CRMs) from mining waste and landfills. The report builds on the conclusions that were obtained during two multi-stakeholder...
On June 21st, Martina Orefice (SOLVOMET Group, SIM² KU Leuven & Early Stage Researcher in the ETN DEMETER project) obtained her PhD degree in Chemistry. She successfully defended her PhD thesis entitled “Solvometallurgical recovery of metal values from Sm‒Co and...
Within the framework of the ETN DEMETER project rare-earth permanent magnets were treated with solvometallurgical solutions of Br2 in organic solvents to remove the metallic coating prior to direct recycling. A comparison with a 2 M HNO3 treatment proved the...
The high thermal stability of Cyphos IL 101 allowed SIM² KU Leuven researchers to investigate the electrochemical behavior of indium at temperatures ranging from 100 °C to 180 °C. The electrochemical deposition of indium followed a two-step process, leading to...
Rare-earths permanent magnets were treated with solvometallurgical solutions of Br2 in organic solvents to remove the Ni-Cu-Ni coating prior to direct recycling. A comparison with 2 M HNO3 treatment proved the advantages of the solvometallurgical process. The...
SOLVOMET is KU Leuven’s Centre for Solvometallurgy. SOLVOMET’s mission is to support its industrial and RTD partners in the conceptual and practical development of more sustainable solvometallurgical separation processes and new mining chemicals, which are subsequently tested using state-of-the-art lab-scale and mini pilot-scale experimental facilities.
