How sustainable is artisanal cobalt mining in DR Congo? That’s the research question which was addressed in a Nature Sustainability paper by a group of researchers of the University of Lubumbashi in collaboration with a team from KU Leuven.
Researchers from the SREMat Group (SIM² KU Leuven) have published a critical review paper on the potential transformation of bauxite residue (“red mud”) into valuable building materials, trying to “put things in perspective”.
Researchers from the ChEMaRTS Research Group (KU Leuven Campus Group T) have developed a method for the extraction of phosphorus from wastewater treatment sludge ash. The work was published in Science of the Total Environment.
Methanesulfonic acid (MSA) has proven again to be a suitable lixiviant for the recovery of valuable metals. Within the SMART project, the SOLVOMET group has developed a solvometallurgical process for the selective recovery of lead and silver from industrial residues.
Rare-earths permanent magnets were selectively roasted with 5 wt.% carbon to obtain a rare-earth phase, separated from iron particles. After mechanical removal of the iron particles, the rare-earth phase was recovered in only 20 min by using the ionic liquid [Hbet][Tf2N].
Neodymium-iron-boron or NdFeB magnets are a vital part of our tech-driven world because of their excellent magnetic properties and versatility
Researchers from the ProcESS and SOLVOMET Group have developed a mechanochemically intensified acid-free leaching process for the recovery of critical metals from NdFeB magnets
Within the SOLCRIMET project (ERC Advanced Grant), SOLVOMET researchers have developed a solvometallurgical process for the separation of yttrium and europium, showing increased efficiency over conventional hydrometallurgical separation routes. The work has been published in Separation and Purification Technology.
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.
