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.
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 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
Recommended or required readings
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)
Assessment methods and criteria
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).

Assessment methods
- You will receive a file in pdf format with all questions by email.
- When opening the email, you will be invited to acknowledge receipt. If it does not prompt automatically, you are supposed to write back a reception email.
- If you have any doubts about a question and need additional clarification, you are invited to write an email to eric.pirard@uliege.be with cc: maxime.evrard@uliege.be . Clarifications will only be given during the first ten minutes of the exam
- You have to answer to all the questions on a blank white sheet with a black or dark blue pen. Write your name, surname on each sheet. You are allowed to answer the questions in any order, but clearly indicate the number of the question before you answer it.
- This is an "open course" exam, you can have all your notes with you. Plagiarism will not be tolerated. Any indication of communication with a classmate or external person will be sanctioned
- After exactly two hours, you will have to send back by email a scan of your sheets (ex OfficeLens app). Format of the scan should be either pdf or jpg. Name the files accordingly ext NAME : your family name course : PM for Process Mineralogy question : "all" or "Q1", "Q2",... for separate answers
- Send the copy to pirard@uliege.be and Maxime.evrard@uliege.be at the correct time. A maximum tolerance of 10 minutes will be allowed, but any later arrival will be sanctioned with a zero! An acknowledgment will be sent upon reception of your exam sheets.
- If you experience any trouble, you are invited to contact professor Pirard directly by phone at his office +32 4 366 95 28
