Projects in Hydrometallurgy cover the recovery of metal from fine shredder residues, the recovery of high technologies metals from electrical and electronic metals, the purification of rare materials, etc.

BIOLIX : Bio-hydrometallurgical recovery of high technologies metals from waste electrical and electronic metals

PHOENIX : Bio-hydrometallurgical recovery of metals from fine shredder residues

SOLARCYCLE : Research and development of technologies for dismantling, desencapsulation, purification and recycling of rare materials in end-of-life photovoltaic units

IPRIS : Improved processing routes for secondary and primary resources used in iron and steel-making

Projects in Geometallurgy are various from geophysical modeling to pulp mineral characterization of particules in pulps. Up to date acquisition and modelling tools are used. Our expertise in modelling,  statistics and artificial intelligence are our added value.

Projects in Sensor Based Sorting and Control use
– sensors such as 3D camera, hyperspectral camera, X-Ray Transmission, Laser induced breakdown spectroscopy for the characterization of particles,
– pattern recognition for the classification and detection,
– robots and pneumatic ejection for the sorting.
