Notes from the Metallurgical Society

  • By AusIMM Metallurgical Society

Hi all, welcome to our latest edition for the AusIMM Metallurgical Society (MetSoc) newsletter.

AusIMM Mill Operators’ Conference

The 14th AusIMM Mill Operators’ Conference is rapidly approaching and promises to be one of the largest Mill Operators’ conferences yet. Celebrating 40 years since this highly successful conference started, the conference will be hosted in Brisbane from the 29-31 August. The committee is pleased to welcome esteemed keynote presentations from Emeritus Professor J-P Franzidis, Neville Plint (Director of the Sustainable Minerals Institute, UQ), Andrew Newell (Executive Consultant in Processing, RPM Global) and Peter Munro (Senior Principal Consulting Engineer, Mineralis Consultants Pty Ltd). To find out more about the conference, and to register, please visit

The inaugural MetSoc Plant Operators’ Forum is a one-day session that will provide a low cost opportunity for operations personnel to engage in discussions on operational challenges and successes covering a wide range of aspects including metallurgical performance, production, maintenance, safety and environmental management. Presentations will be given by operations-based personnel from a diverse range of companies including Newcrest, Evolution, Independence Group, Goldfields, Newmont, AngloGold, PanAust and Agnico Eagle.

Topics cover several aspects of plant operations including safety, geometallurgy, flotation, process optimisation and tailings management. The program will allow for opportunities for attendees to discuss the presentations, table specific issues or topics relevant to their site and to participate in discussion forums on all relevant aspects of plant operations.

The MetSoc Plant Operators’ Forum will be held ahead of the Mill Operators’ Conference on Tuesday 28 August in Brisbane. Register here and join us for what will be an enjoyable and productive workshop.

There are also two additional workshops being held post the conference, on Saturday 1 September:

W2: Geometallugry and Mineralogy for Mineral Processing, and

W3: Lithium Ore Processing.
