On-line quantification of solid-phase metal extraction efficiencies using instrumented millifluidics platform

Urban mining of unexploited spent critical metals from E-waste made possible using advanced sorting

“…Indeed, such elementally enriched fractions can either be traded or purified by hydrometallurgy. In the latter case, one still has to face the issue of the variability of the composition of the sorting bags, which can be solved thanks to state of the art microfluidics based rapid process development tools (Maurice et al 2022;Olivier et al 2022Olivier et al , 2023.…”

Printed circuit board recycling: a focus on a novel, efficient and sustainable process for spent critical metals recovery

“…By eliminating the presence of undesirable elements and enriching the streams with targeted elements, the process contributes to creating more homogeneous streams, thus facilitating their subsequent treatment. Furthermore, the development of microfluidic platforms [31] fully integrated with on-line characterization methods, such as FTIR [32] and XRF [8], will ensure the cost effective and fast development of new hydrometallurgy processes, whether liquid-liquid [33][34][35], solid-liquid [36] or for the measurement of thermodynamic data such as components chemical activities, including for the solvent [30,32].…”
