Particle size and shape are known to influence strongly rheology, reactivity, abrasivity but the are however most of the time very poorly characterized.
Image-based technologies provide a range of solution for the size and shape characterization of particle at every scale from the decimetric scale, to evaluate the efficiency of blasting to the micro-scale and the evaluation of particles sizes in process water.
Partners of the OREVAL are developing prototype applications to continuously measure particle size distribution on mining plant.
Particle size evaluation is also of great importance for the monitoring of agglomeration process, the evaluation of tailing materials properties and the valuation of mining residues as building materials substitutes.
Accurate particle size measurement is also determining for image-based quantitative mineral analysis.
