SULTAN, the EU Training Network for the remediation and reprocessing of sulphidic mining waste sites, has launched its long-awaited Thematic Section in the Journal of Sustainable Metallurgy, comprising 10 research papers.

Within the EU H2020 ETN SULTAN project, Wienerberger, VITO & SIM2 KU Leuven researchers succeeded in blending up to 20 wt% of mining waste into ceramics. The work was published in the Journal of Sustainable Metallurgy.

The 2-day symposium “(Re)Mining extractive waste, a new business?” gathers leading experts in the field of (re)mining of mining-related waste, with a focus on the tailings that arise during the mining and processing of sulphidic ores.

Researchers at KU Leuven have started up a leaching and solvent extraction pilot, for the separation and purification of rare-earth elements. These pilots are constructed and operated within the EU Horizon 2020 NEMO project, aiming at the valorisation of sulphidic mining waste

Within NEMO project, TERRAFAME will run a pilot operation for more than one year to enhance bioleaching heap efficiency and to increase metal recovery from secondary ores.

SIM² KU Leuven - SOLVOMET/PROCESS researchers developed a new method for the measurement of chlorides in ionic liquids using wavelength dispersive X-ray fluorescence (WDXRF). The work was published in ACS Omega.

SOLVOMET/SIM² KU Leuven researchers developed a predictive molecular thermodynamic model, enabling a more efficient design of future (battery-grade) cobalt solvent extraction flowsheets. The work was published in ACS Omega.

On April 27 more than 220 people participated in the event “Can the recycling of mining waste become a new business?” Three experts from EC DG ENV, Boliden & Cronimet shared their views. Here are the main lessons learned...

SOLVOMET/SIM2 KU Leuven & VITO researchers developed a process to recover copper from dilute ammoniacal leachates of microwave-roasted Cu-Zn-Pb sulphidic tailings. The work was published in Journal of Sustainable Metallurgy.

Within the ETN SULTAN project, Wienerberger & SIM² KU Leuven researchers studied the potential blending of sulfidic mining waste in new ceramic roof tiles and blocks. The work was published in Journal of Geochemical Exploration.
