Marandoo Optimisation
Rio Tinto Iron Ore
Pilbara Region, Western Australia, Australia
Increasing throughput from 12Mtpa to 15Mtpa.
Calibre QuadR was appointed as the engineer to conduct a three-month study during which the following was critically examined:
- Mine and plant operations
- Performance of process plant including observations and testing
- Process control systems
- Mine plan and ore types expected
- Proposed scope of work
Further to the study recommendations, our team:
- Recommended the planned addition of a second scalping screen be excluded from the scope as it would be adverse to plant performance
- Recommended the planned replacement of the vibrating feeders with belt feeders be excluded from the scope
- Recommended splitters for the lump and fines products to match the revised lump/fine ratios
- Replaced product screen mats
- Updated the process automation system
- Upgraded the major conveyor drives to debottleneck, and
- Replaced transfer chutes to better handle the “wetter” ores
