About the role
This interview focuses on leading a mineral processing plant through changing ore, equipment constraints and production pressure. The panel wants evidence that you can diagnose performance, run disciplined improvements, protect safe operating limits and coordinate metallurgical, laboratory, maintenance and production teams.
How to prepare
- Prepare a clear account of a recovery, throughput or product quality problem you solved.
- Review how you validate plant sampling and distinguish a real trend from bad data.
- Think through the operating response to loss of power, water or critical equipment.
- Revise how ore variability affects the main stages of your relevant processing route.
- Prepare an example of balancing maintenance work with production commitments.
Common mistakes
- Offering a reagent or set-point change before checking sampling, instruments and ore characteristics.
- Claiming an improvement from a short trial without considering variability and repeatability.
- Treating maintenance and laboratory teams as support functions rather than operating partners.
- Discussing production gains without their safety, product quality or cost consequences.
