Learning outcomes of the learning unit
- 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
- Be able to build recovery curves and develop a geometallurgical approach in processing complex and low grade ores
Prerequisite knowledge and skills
Basic Mineralogy Course
Notions of Mineral Processing
Planned learning activities and teaching methods
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.
Whenever possible scholars (expert researchers) are invited to present insights into the most advanced and innovative technologies (ex. X-Ray tomography; automated mineralogy;...).
Mode of delivery (face-to-face ; distance-learning)
- 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

Assessment methods and criteria
Written examination (80%) consists 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.
The practical works handed over by students during the year contribute to the final mark of the course:
- Report on particle size distribution analysis (5 %)
- Report on image analysis (5%)
- Report on XRD (and ICP) result analysis in the Mineral Processing Project (5%)
- Mineralogical Analysis of the results of the Mineral Processing Project (5%)
