Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

  • Understand qualitative and quantitative analytical mineralogy techniques essential for monitoring mineral processing operations.
  • Be able to use them appropriately and to make a sound data interpretation
  • Be able to cross-correlate the results of the different techniques for validation
  • Make use of the obtained mineralogical data to balance unit operations and identify issues related to elemental deportment in the process

Activités d'apprentissage prévues et méthodes d'enseignement

Lectures are delivered in a classroom allowing for spontaneous interaction between professor and students. The lessons use PPT with images of microscopic ore textures.
 
Every (2h) lecture is complemented by a (2h) practical session on the instruments presented during the course. The students are given real ore samples on which they have to perform a series of analyses and report in written form about their findings. Ideally the samples are those on which they work in the mineral processing course so that the analytical information gathered during these practical sessions serves for the interpretation of recoveries obtained in the mineral processing lab.

Reflected light Optical Microscopy on a variety of ore samples is organized both in the lab and with virtual acccess. Identification of ore minerals is a key competence to develop during the course.

Whenever possible scholars (expert researchers) are invited to present insights into the most advanced and innovative technologies (ex. X-Ray tomography; automated mineralogy;...).

Mode d'enseignement (présentiel, à distance, hybride)

  • Frontal instruction (2h) to explain the principles, capabilities and limitations of the techniques
  • Hands-on learning (2h) on real ore samples using a variety of techniques
  • Written report and face-to-face discussion with young researchers about results

Supports de cours, lectures obligatoires ou recommandées

Required :
Power Point presentations available through the student portal (MyULg)
 
Recommended:
Process Mineralogy, M.Becker, E Wightman and C Evans (editors), JKMRC Monograph Series (2017)

Explications complémentaires:

80% : Written examination consisting in a series of questions relating to both a sound understanding of the underlying principles and to the proper interpretation of data collected from real case studies.

10% : Practical works handed over by students during the year (particle size analysis, image analysis,...) contribute to the final mark for 10%. The scientific rigor, clear structure and illustration as well as care taken in the presentation are essential criteria in the evaluation.

10% : Practical examination in optical ore microscopy (on site or virtual).
