This, the 11th International Comminution Symposium (Comminution '18) is organised by MEI in consultation with Prof. Aubrey Mainza and is sponsored by Magotteaux, Keramos, Russell Mineral Equipment, Starkey & Associates, Grinding Solutions, King's Ceramics & Chemicals, Loesche, TOMS, ZEISS, FLSmidth, Outotec, Cenotec & CHEMCO Advance Material. Media sponsors are International Mining and the Coalition for Eco-Efficient Comminution (CEEC) are industry advocates.


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



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 published as an unrefereed Proceedings on a USB memory stick, and selected papers will be published, after peer-review, in a special Comminution issue of Minerals Engineering journal.



The first keynote lecture, "Comminution in 2068 - will SAG mills still be relevant?" will be presented by Prof. Holger Lieberwirth of TU Bergakademie Freiberg, Germany.

Holger Lieberwirth studied in Dresden and Kiev in mechanical engineering with a focus on mining machinery. Between 1989 and 2013 he held technical and management positions with equipment manufacturers supplying mainly to the resource industry. Projects spanned the whole world from Freeport, Indonesia, to Syncrude, Canada. Since 2013 he has been Professor at the Technical University Bergakademie Freiberg, and director of the Institute of Mineral Processing Machines.

The second keynote lecture, "Superior comminution circuit performance: integrating classification during design is the key" will be given by Prof. Aubrey Mainza, of the University of Cape Town, South Africa.

Aubrey Mainza is a Professor in the Department of Chemical Engineering, University of Cape Town (UCT). He graduated from UCT with a PhD in 2006. He has 18 years of collective experience in academia, research and industry. He is the Deputy Director and Head of Comminution and Classification Research in the Centre for Minerals Research, which is a large multi-disciplinary research centre. His research areas include comminution and classification and uses Discrete Element Method (DEM), Computational Fluid Dynamics (CFD), and Positron Emission Particle Tracking (PEPT) as tools in his modelling methods. He has participated in many local and international research projects and has worked on numerous comminution circuit design and optimisation projects. He is an active supervisor of postgraduate students and has published widely in the international mineral processing and aligned disciplines literature. He is the chairperson for the International Comminution Researchers Association African Chapter and committee member the Western Cape Branch of the Southern Africa Institute of Mining and Metallurgy. Aubrey is on many advisory committees for international conferences. He is a founder member of PEPT Cape Town, a facility established in Cape Town for studying flow behaviour in different systems and also for medical research.

Comminution '18 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.

"A thoroughly enjoyable experience [Comminution '16]. It was interesting to look at the comminution business from a slightly different angle. Most of us commercial people specialise in a specific area, so good to see what everybody else is doing."
Tim Lane, Sales and Marketing Engineer, Crushing and Screening, Sandvik Mining, South Africa

"Another excellent conference [Comminution '14] ... There was a very good mix of industrial and academic papers/posters stimulating a lot of discussion and exchanges. Looking forward to Comminution '16!"
Peter Radziszewski, Metso, Canada

"I'd just like to thank you and the family for putting together a very enjoyable, informative and thoroughly professional conference last week in Cape Town [Comminution '10]. Very pleased to hear we'll be back there in two years. Once again thank you very much it was one the best run events I have attended."
Dave Capstick, Director Sales, Deswik Mining Consultants (Pty) Ltd, South Africa

"I congratulate you for a very successful conference. Thank you very much for everything.
I met valuable colleagues which may result in lasting relationships. This Comminution 08 conference did move my career forward in a meaningful way. It was one of the most productive conferences I have ever attended."
Prof. Tarik Ozkahraman, University of Suleyman, Turkey

"It was my first visit to the Comminution conference [Comminution 08] and I would like to send you and your family my thanks and appreciation for an excellently organized meeting. I am looking forward to participating in your future meetings."
Boris Farber, Zircoa Inc., USA

"Thank you for providing a valuable comminution forum [Comminution 04] in Perth. We enjoyed being associated with this conference and the exposure it brought with it."
Sarah DeBono, Senior Process Engineer, Xstrata Technology (sponsors of Comminution 04, Comminution 06 & Comminution 08)
