Occurrence of rare earths in post-processed bauxite residue

Occurrence of rare earths in post-processed bauxite residue

In the framework of the European Training Network for Zero-Waste Valorisation of Bauxite Residue (REDMUD), the occurrence mode of selected rare-earths in post-processed bauxite residue was studied by KU Leuven and the National Technical University of Athens. The work...
Deep Eutectic Solvents for solubilisation of metal oxides

Deep Eutectic Solvents for solubilisation of metal oxides

Within the strategic basic research project SMART, funded by the Flemish government under the SIM MARES programme, KU Leuven develops novel solvometallurgical approaches for the valorisation of industrial residues from the mining industry. In this work, attention is...
Selective metal recovery from Fe-rich industrial residues

Selective metal recovery from Fe-rich industrial residues

Within the EU H2020 SOCRATES project, a process was developed by the SOLVOMET Group within SIM² KU Leuven to selectively recover lead and zinc from Fe-rich industrial residues (i.e. jarosite residue of the zinc industry) using ionic liquids Aliquat 336 ([A336][Cl])...
Why restricting lead (Pb) metallurgy is a bad idea

Why restricting lead (Pb) metallurgy is a bad idea

During the last few years, the use of lead (Pb) in the EU economy has been called into question by some policy makers. Lead is frequently seen as a problematic metal that can be detrimental to human health; what is much less well known is its fundamental role in the...
Ionic liquids for REE recovery from lamp phosphor waste

Ionic liquids for REE recovery from lamp phosphor waste

Within the EU H2020 REMAGHIC project, KU Leuven developed a process to recover yttrium and europium from a mixed oxide obtained by the processing of lamp phosphor waste based on solvent extraction with undiluted thiocyanate ionic liquids. The work is published in the...
Selective REE recovery from bauxite residue slags

Selective REE recovery from bauxite residue slags

In the framework of the European Training Network for Zero-Waste Valorisation of Bauxite Residue (REDMUD), an integrated process was developed by KU Leuven and RWTH Aachen University to selectively recover metallic iron and rare earths elements from slags produced...
