Morobe Consolidated Goldfields Limited, a subsidiary of Harmony Gold, has been operating the Hidden Valley Gold and Silver mine in Papua New Guinea. In 2021/2022, the company installed six Mintek online carbon concentration meters (C2 Meters) in their Carbon-In-Leach (CIL) circuit to evaluate the benefits of real-time carbon measurement for automated carbon management.
- Improved Carbon Management: Real-time carbon measurements led to an 89% reduction in fresh carbon consumption rate.
- Reduced Gold Losses: Gold solution losses to the CIL final tails were reduced by 45%.
- Automated System: C2 Meters eliminated manual entry and automated carbon movement sequencing.
- Reliable Measurements, Accurate Inventory: C2 Meters provided reliable measurements, ensuring accurate estimation of carbon inventory for optimized metal recoveries.
