About the role

This internship interview checks whether you can apply classroom process principles in a working mineral plant or test laboratory. The panel is looking for curiosity, careful sampling and calculations, respect for experienced operators and a strong instinct for safe working.

How to prepare

  1. Revise the purpose of crushing, grinding, classification and common separation stages.
  2. Practise a simple mass balance and explain what an impossible result would tell you.
  3. Review representative sampling, sample labelling and contamination control.
  4. Prepare an example of learning from a practical test that did not behave as expected.
  5. Study the hazards around moving machinery, slurry, reagents and poor housekeeping.

Common mistakes

  • Reciting process definitions without connecting them to product size or separation performance.
  • Ignoring an impossible calculation instead of checking measurements and units.
  • Approaching live plant equipment without first following the required safety procedure.
