Practicals

64 hours of practicals To be conducted online or on-campus or in-house
Overview

Practical sessions are integral to this course, allowing learners to apply process control theory to simulated and actual PGM production scenarios. Learners operate pilot-scale equipment, calibrate instruments, adjust process parameters, and troubleshoot deviations under supervision, reinforcing the skills needed for effective process control.

Practical Activities
  • Practical 1: Leaching Process Control — Learners operate a pilot-scale leaching reactor, adjusting temperature, pressure, and reagent feed rates while monitoring pH and ORP to achieve target dissolution efficiency. (16h)
  • Practical 2: Precipitation and Filtration — Learners perform selective precipitation of platinum and palladium from simulated solutions, controlling pH and reductant addition, then filter and wash the precipitate. (16h)
  • Practical 3: Calcination and Product Quality — Learners operate a small calcination furnace, setting temperature profiles and atmosphere, then characterize the sponge product for surface area and purity. (16h)
  • Practical 4: Process Control Simulation and Troubleshooting — Using a process simulation software, learners design control strategies for a PGM production line, respond to simulated disturbances, and implement corrective actions. (16h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total
Component Out of Weight
Practical Assignments (rubric-scored) 100% 30%
Daily Average (multiple choice) 100% 20%
Final Test (multi-answer multiple choice) 100% 50%
Final Total 100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

Certificate of Completion

Awarded to delegates who achieve an overall mark of 50% or higher on the Final Total (Practicals 30% + Daily Average 20% + Final Test 50%).

How it works
  • Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
  • Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
  • You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
  • If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.
