GeMMe

GeMMe is a unique research group in Wallonia contributing to the development of innovative processes for an efficient management of mineral and metallic resources. Taking its roots in the traditional disciplines of mining, metallurgy and civil engineering, GeMMe experienced a deep mutation of its activities within the last ten years by making use of its know-how to unlock the values in industrial solid wastes, end-of-life consumers goods and complex georesources.

GeMMe is divided into three research units:

The Georesources-GeoImaging group led by Prof. Eric Pirard specializes in the development of vision-based characterization tools from outcrops to nanosized particles.

The Mineral Processing & Recycling group under the responsibility of Prof. Stoyan Gaydardzhiev focuses on energy- and water-efficient processes in the comminution and treatment of ores and inorganic wastes.

The Construction Materials group headed by Prof. Luc Courard develops new and eco-friendly building materials making effecient use of industrial residues.

Each of these research units is backed by a well-equiped experimental lab to help develop its activities through a strategic innovative approach:

Laboratoire des Matériaux de Construction under the direction of Ir. Frédéric Michel

Mineral Processing, Process Mineralogy & Recycling Lab under the direction of Ir. David Bastin

Research

Our main activity is the research.

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.

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.

Projects in Physical pre-processing use one of our common or remarkable equipment such as the Electrodynamic Fragmentation to selectively fragment products of interest.

 

Laboratories

GeMMe laboratories are dedicated to the research as well as the services for industrial partners.

Services to industrials are for instance
– Construction Materials caracterization
– Formulation of concrete
– Mineral Preprocessing
– Hydrometallurgy
– Automated Mineralogy
– 3D, VNIR, SWIR, XRT imaging
– XRT, XRF analysis
