Challenge
- Achieve a step-change improvement in copper concentrate burner-combustion performance to debottleneck production at the Olympic Dam smelter.
Solution
- Developed innovative, patent-pending swirl disperser technology.
Highlights
- Exceptional improvement in burner-combustion efficiency
- Reduced oxygen and fuel consumption
- Increased throughput and smelter availability
“In addition to the other benefits, the new disperser has significantly improved process stability.”
