Expertise and facilities

We are an 11-partner network with expertise in…

  • Particle size and shape

    Particle size and shape are of much importance in many processes. They are known to influence strongly rheology, reactivity, abrasivity but the are however most of the time very poorly characterized.

    Although well-established and afordable technologies are available and in-use in other powder related industry sucha as foods or pharmaceutics.

  • Design and Modeling

    Mineralogy plays an important role in the efficiency of any mineral processing plant.

  • X-ray Computed Tomography

    3D imaging and characterization using X-ray CT technology and 3D image analysis allows the non-destructive imaging of the 3D structure of geomaterials, from the nano- to macro-scale at high temporal and spatial resolution.

    This technology enables real-time imaging of processes in the pore space under controlled environmental conditions: T°, RH, compression, fluid flow, etc.

    Both in-house build and commercial systems are available in the network. We also have a unique expertise in 3D reconstruction.

  • Automated Mineralogy

    SEM-EDX based system for Mineral Liberation Analysis (MLA) was the major technological breakthrough of the last decade in the field of applied mineralogy. OREVAL Network povide acces to all the major commercially available MLA systems on five distinct locations.

    All partners toegheter have extensive experience handling the equipment in various geological context.

    Partners are actively carrying out research in the field of correlative microscopy which through the use of complementary technics (optics-based, micro-focused XRF, etc) will be the core of the next generation MLA systems.

  • Electron Micro Probe

    Electron Microprobe Analysis is a technique that enables minerals mapping of trace element. Thank to the use of multiple Wavelength dispersive X-ray detector (WDS) the detection limit can be as low 100 ppm.

    EMPA is very usefull as a complementary tool to EDS mapping. It enables an accurate validation of EDS database.

  • Hyperspectral Imaging

    A common application of hyperspectral imaging of the field of geology is to record infrared data map that can be further classified in order to identify different type of minerals. Infra-red spectra is especially useful for the identification of some clays minerals or in the discrimination of different iron oxides species. In the OREVAL network we are developing or own software to classify minerals and to use the technology on new applications or in combination with other technology.

  • Image analysis

    Image analysis and image processing are fundamentals to the valuation of the huge amount of data made available by the wide range of imaging techniques available on the market today. Images analysis enable to turns images into figures that can be further use in any decision or optimization process.

  • Core scanning

    Systematic core scanning coupled to proper storage and display is a powerful tool for the accurate modeling of ore deposit.

    DMTCoreScan is a high quality scanning device ranging from UV light to near infrared. The device lately integrates a LIBS system that complement the image with chemicalal data composition.

    DMT industrial expertise is complementary to research project on Core Scratch mechanical testing and short wave length infrared system developed at the University of Liège.
