Within the SOLCRIMET project (Advanced ERC Grant) Zheng Li et al. (KU Leuven) and colleagues from the University of Texas (Austin) have developed a solvometallurgical process for the separation of GaCl3 and AlCl3. The work has been published in Ind. Eng. Chem. Res.
CaO-FeOx-SiO2 slags can be used as raw material for alkali-activated materials, i.e. a green alternative to Portland cement. In Cement and Concrete Research, KU Leuven & Princeton University researchers reveal new insights into the reaction mechanisms.
Within the SOLCRIMET project (ERC Advanced Grant), Zheng Li et al. discovered that selection of suitable polar solvents can enhance metal separations in liquid-liquid extraction. The work has been published in Chem. Eur. J.
Within the SMART project, Nerea Rodriguez et al. have shown that Deep Eutectic Solvents based on carboxylic acids and choline chloride are not stable in time nor at high temperatures. The work was published in ACS Sustainable Chemistry & Engineering.
The high thermal stability of Cyphos IL 101 allowed SIM² KU Leuven researchers to investigate the electrochemical behavior of indium at temperatures between 100 °C and 180 °C. The electrochemical deposition of indium followed a two-step process. The work was published in Green Chemistry.
Within the framework of the ETN DEMETER project rare-earth permanent magnets were treated with solvometallurgical solutions to remove the metalllic coating prior to direct recycling. The work is published in RSC Advances
Germanium is a precious metal which is mainly used as a semiconductor in electronics and infrared optic industries, and as a polymerisation catalyst for the production of polyethylene terephthalate. Due to its high supply risk and its high economic importance, germanium is considered as one of Europe’s critical metals.
A solvometallurgical route for recycling of SmCo permanent magnets was developed by researchers from the SOLVOMET Group (SIM² KU Leuven). The method is based on non-aqueous solvent extraction to minimize water consumption.
The work is published in Separation and Purification Technology.
In the framework of the EU MSCA-ETN REDMUD project, the occurrence mode of selected rare earths in neutralised-leached bauxite residue was studied by KU Leuven and NTUA. The work is published in Journal of Sustainable Metallurgy.
The SOLVOMET Group (SIM² KU Leuven), which develops solvometallurgical flow sheets, has synthesized new Deep Eutectic Solvents that can selectively dissolve metal oxides from industrial residues derived from the mining industry.
