Masterclass Kalgoorlie 2025

Participants qualify for six Professional Development (PD) hours.

Join Molycop experts in Kalgoorlie, Western Australia, for an insightful Masterclass event that will include presentations on milling fundamentals, grinding media interactions, analysing plant trials, turning data into results and the Mill Family Model.

The event will be followed by networking drinks, offering an informal opportunity to discuss optimising plant performance.

Program

Morning tea and networking (9:30-10:30am)

Morning session: 10:30–12pm (1.5 hours)
Optimising milling performance – From fundamentals to practical plant trials

Presenters: Danh Chung/Giehard Nebre (optional)

Milling fundamentals: A practical overview of comminution, covering the role of the mill, key operating parameters and their influence on grinding efficiency and throughput.
Grinding media interactions: How ball size and ball charge volume influence breakage, energy use and overall milling performance.
Analysing plant trials: A step-by-step look at how to design, conduct and interpret plant trials to evaluate operational changes.

Lunch (12:00–1pm)

Afternoon session #1 (1–2:30pm)

Molycop technology/innovation – Turning data into results: Optimisation for milling, leaching and flotation

Presenter: Pieter Strobos

Achieving real optimisation gains using instrumentation, advanced control, process modelling and data analytics.
Proven strategies to boost throughput, recovery and efficiency – regardless of ore type.
Drawing on five years of Molycop projects in milling, leaching and flotation, Molycop will share real results:
- 5–27% increases in throughput.
- 1–3% improvements in recovery.
- 10–30% reductions in cyanide use.

Tea break (2:30–2:45pm)

Afternoon session #2 (2:45–4:15pm)
Molycop technology/innovation – Mill Family Model: A data-driven approach to smarter grinding media selection

Presenter: Dr Yufan Mu

Select the right grinding media to maximise mill performance, control costs and meet sustainability goals. Variations in ore, mill setup and operating conditions often make this a complex decision.
Learn about the Mill Family Model, which uses machine learning to group SAG and overflow ball mills into 'families' with similar grinding environments. These clusters reveal dominant wear mechanisms – impact, abrasion, and corrosion – building more precise media selection.
Understand the model's methodology, gain insights from industrial datasets and learn how they help make the choice between forged steel and high-chrome media. By reducing trial-and-error, the model enables faster, more consistent decisions, improving media performance, shortening test cycles and supporting long-term sustainability.

Drinks and networking (4:15pm onwards)
