4. Lab-scale ion-exchange chromatography studies

Lab-scale ion-exchange chromatography studies allow the design of a metal-separation process using ion-exchange resins, which are mostly suitable for the selective valorisation of various diluted streams and solutions. The study includes the design of tailor-made adsorbents and/or the screening of commercially available adsorbents. The best performing adsorbent will be tested in batch adsorption experiments to fully characterise its chemistry towards the targeted metals and several parameters will be optimised. Finally, the adsorbent will be applied in a lab-scale chromatography set-up.

Available equipment: stirring plates, orbital shakers, column chromatography set-ups.


Column chromatography Custom-build

The Ismatec IPC 8-channel peristaltic pump, in combination with the Spectra/Chrom CF-2 fraction collector can be used for liquid chromatography. Fractions can be collected based on time, volume or number of drops. Flow rates between 0.002 and 44 mL/min can be achieved. A large variety of columns are available, which can be packed with an adsorbent of choice.



SOLVOMET ISC is KU Leuven’s Industrial Service Centre for Circular Hydrometallurgy. We support mining, metallurgical & recycling companies in the development of more sustainable (circular, low-energy input) hydrometallurgical processes, using state-of-the-art lab & mini-pilot scale experimental facilities.
