This, the 8th International Comminution Symposium (Comminution '12) was organised by MEI in consultation with Prof Malcolm Powell and Dr. Aubrey Mainza. It was sponsored by Starkey & Associates, Magotteaux, Maelgwyn Mineral Services, JKTech, Chemco Advance Material, Industrie Bitossi, Xstrata Technology, DMM, Metso, Keramos, Cenotec, Weir Minerals, TOMS, Sinoma Advanced Materials, FLSmidth, Industrial Minerals, International Mining, & The Gold & Minerals Gazette.
THEMES
Designing for the concentrator of 2020 - what are we contributing?
Are we taking up the challenge of providing the leadership and required tools to design our future concentrators? This is surely where we can make the most significant contribution to our industry.
If you are contributing as a researcher, supplier, engineering company or as a development team in mining company then let’s hear from you. We encourage the end-user companies to bring their needs and drivers to the table so as to motivate the development of appropriate expertise and technology and to pick out the potential useful contributors to your development vision.
Industry keynote speakers are being invited to present the vision and challenges.
As a research or technology provider, come and show us what you’ve got!
The following broad themes are likely to address this area:
- Improving environment sustainability while driving down costs
- Designing and operating energy efficient circuits
- Designing for the next generation of mines
- Pre-concentration – ore sorting, gravity, dense media, coarser liberation
- Reducing the costs of consumables – energy and dollars
- The push to finer grind for new ore bodies
- Design of stirred mills – higher capacity, coarser feeds, media wear, energy consumption
- Progress in modelling and scale-up
- Rheology – wet and dry
- Influence on classification and fine milling
- Fine screening
- Benefits, costs, feasibility
- Compressed bed breakage
- Dry grinding and classification ahead of wet recovery processes
- Driving into finer grinding
- Integrating new equipment and ideas into practical circuits
- HPGR’s, dry classification, fine screening, sorting and separation, mixed milling HPGR circuits, coarser flotation
Draft papers have been published as an unrefereed Proceedings on CD-ROM, and selected papers will be published, after peer-review, in a special Comminution issue of Minerals Engineering journal.
KEYNOTE LECTURES
|
Chris Rule, of Anglo American Platinum, South Africa presented "2020 - what will the typical PGM Concentrator flowsheet look like?"
Chris has been a metallurgist in the PGM industry for more than 30 years after graduating with a MSc at Imperial College, London in 1979. Uniquely, he has worked with and for all the major PGM producers in this time and has extensive experience in production, project design and execution and technical support to operations and technology commercialization. Currently in his role at Anglo American Platinum he is responsible, amongst other duties; for the introduction of the successful stirred milling projects and the implementation of new and innovative processing flow sheets.

Dr. Ted Bearman presented the keynote lecture "Step Change in the Context of Comminution"
Ted, Director of Bear Rock Solutions Pty Ltd, Australia has held a variety of technical and managerial roles over the last 24 years. Much of his experience has been in the optimization of mining and processing operations. In addition Ted has been involved in the design and manufacture of comminution and processing equipment, including research and development of new machines and technology. In his last corporate role Ted was a General Manager for Rio Tinto in the innovation space and prior to that led the comminution effort for their internal Technical Services Division. He now runs his own consulting business and is actively engaged in a range of strategic and tactical studies.

ORGANISERS
|
Comminution '12 was organised by MEI in consultation with Prof Malcolm Powell and Dr. Aubrey Mainza.
In 1997 Prof Malcolm Powell formed the comminution group at the University of Cape Town, following the suggestion of Prof Cyril O'Connor (director of the Mineral Processing Research Unit MPRU) - after a memorable MEI conference in Cornwall. From January 2007 Malcolm has joined the JKMRC of the University of Queensland to take up the Chair in Sustainable Comminution.
Malcolm specialises in mill liner design, charge motion and DEM modelling, SAG mill modelling, and classification, with a strong link into applying the research knowledge in extensive site work and consulting to industry. The work aims to link fundamental research into applied outputs through the development of practical and robust process models.

Dr 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.
