MEI Online: MEI Conferences: Process Mineralogy '18: Introduction

Home General Introduction Conference Report Conference Programme Published Papers Delegate List Photos Contacts Process Mineralogy '20  


This, the 5th International Symposium on Process Mineralogy (Process Mineralogy '18), was organised by MEI in consultation with Dr Megan Becker and was sponsored by ZEISS, Bruker, Thermo Fisher Scientific and Petrolab. Media sponsors were International Mining and the Mining Reiew Journal Zambia.



Developing from MEI’s previous conferences on Process Mineralogy, Applied Mineralogy and Automated Mineralogy, Process Mineralogy ’18 dealt with the following topics:

  • Quantitative mineralogy, including both X-ray and Electron Beam Techniques
  • Geometallurgy
  • Ore characterisation
  • Mineral Liberation and Textural Analysis
  • Application of process mineralogy on site
  • Sampling and Statistics
  • Advanced Process Control

Papers were published as an unrefereed Proceedings on a USB Memory Stick, and selected papers will be published, after peer-review, in a special Process Mineralogy virtual issue of Minerals Engineering journal.




ZEISS ran a pre-conference workshop on Sunday 18th November at the conference venue, the Vineyard Hotel, from 1pm – 4.30pm.

The theme of the workshop was based around the circular economy and improvements to existing mineral processing techniques to reduce carbon footprint.

Confirmed speakers:

  • Nick Wilshaw, Grinding Solutions
  • James Strongman, iMIN Solutions
  • Dr. Pieter Botha, Hippo Geoscience
  • Shaun Graham, ZEISS Microscopy
  • Desh Shetty, Mintek (tbc)
  • University of Liege (tbc)

Session Chairs:

  • Dr. Megan Becker, University of Cape Town
  • Dr. Ben Tordoff, ZEISS Microscopy




Process Mineralogy '18 was organised by Minerals Engineering International (MEI) in consultation with Associate Professor Megan Becker.

Megan Becker leads the geometallurgy and process mineralogy research activities in the Centre for Minerals Research, and the Minerals to Metals Initiative in the Department of Chemical Engineering at the University of Cape Town. She has a background in geology (BSc Hons, MSc - University of Cape Town) and a PhD in process mineralogy from the University of Pretoria (2009). Her research interests focus on understanding the effects of mineralogy on minerals processing, metallurgy and the environment, and how best mineralogy information be articulated and communicated to maximise the value of minerals to society. She has conceptualised, designed, developed and run courses in process and applied mineralogy at both the undergraduate student level and industry professional development level. To date, she has supervised 30 postgraduate students, has 70 peer reviewed publications. After having recognised the complete lack of relevant reference texts on process mineralogy in 2011, she initiated a Monograph on Process Mineralogy. She was the lead editor of this Monograph, published in 2016 through the Julius Krutschnitt Mineral Research Centre. The text contains over 30 peer reviewed chapters written by international experts in the field of process mineralogy.
