The mandate
Integrate major upgrades into live operations
Apply Bayer-process expertise to expansion projects across the calciner, liquor purification unit and lime kiln while maintaining shipping quality and operational readiness.
Selected outcomes
Evidence of progress
- $4b
- G3 expansion program
- 3
- Major process systems upgraded
- Bayer
- Circuit-wide process expertise
How the work was approached
From intent to operating capability
Work across the process chain
Engineering covered digestion, evaporation, classification, filtration, calcination and lime systems rather than treating each upgrade in isolation.
Connect projects with operations
Commissioning and readiness work focused on stable integration, maintainability and the practical needs of refinery teams.
Protect the product
Shipping-quality requirements remained a core constraint throughout process changes and expansion activity.
Work delivered
What changed in practice
- Contributed to calciner and lime-kiln upgrades.
- Supported development and optimisation of liquor purification.
- Maintained attention to smelter-grade alumina shipping quality.
Perspective
Expansion work succeeds when new equipment improves the system operators actually have, not the system imagined on a process diagram.
