"Comminution must be the key mineral processing technology during the next 50 years." - Prof. Alban Lynch (August 2013)



After much deliberation, MEI have decided that Comminution '21 will take place online next year. The current restrictions on travel and meetings do not look like they will ease any time soon and we are excited by the possibilities offered by moving online.

Look out for a new website coming in the next few weeks. It will have full details of how the online event will work, including the Virtual Exhibition and new registration fees.

If you have any questions please contact one of the team.



MEI's Comminution conferences are established as the main events for profiling cutting edge research and innovation in all aspects of crushing, grinding and ultrafine grinding in the minerals industry.

We strongly encourage a good balance between industrially based and academic research papers showing the benefits of basing practical application on scientific rigour, such as the industrial validation of models and control techniques.


"Comminution '14 not only enhanced my knowledge but also helped me identify solutions to the milling circuit I manage. Some of the discussions we had, we have carried them forward as part of the business process improvements. I also managed to identify with a huge pool of knowledgeable people from across the world. I could not imagine communicating daily and interacting with people from SA, USA, France, Iran, China, Australia and various other countries."
Clifford Farai Mutevhe, Anglo American Platinum, Zimbabwe


Draft papers will be requested for the online event and selected papers will be published, after peer-review, in a special Comminution issue of Minerals Engineering journal.



Comminution '21 is organised by MEI in consultation with Prof. Aubrey Mainza.

Prof. Aubrey Mainza graduated with a Bachelor of Science (majoring in Metallurgy and Mineral Processing) from the University of Zambia in 1998. He completed his PhD in Mechanical Engineering (specialising in the areas of comminution and classification in mineral processing) at UCT in 2006. He joined the Centre for Minerals Research as a Research Officer in 2002, then became a Senior Research Officer, and is now a Senior Lecturer in the Centre. Today Aubrey heads CMR's Comminution research, teaches core Chemical Engineering, and participates extensively in collaborative research with international universities, mining companies, and comminution and classification equipment manufacturers.
