Metal Ore processing
Innovative solutions for sustainable Metal Ore processing
Metal Recovery
Opale™ Solution technology added between the milling and the flotation process will enhance the slurry particle state of dispersion and flotation reagent selectivity to improve metal recovery and concentrate grade quality.
Key benefits
- Better state of dispersion
- Reagent selectivity improvement
- Optimized metal recovery

Rheology modifiers to improve flotation metal recovery
Hydro-transportation
Rheology issues are often met during concentrate and tailings transportation or thickening steps due to ore quality (clay presence) and/or equipment limitation.
Thanks to a unique mechanism, Opale™ Solution polymers will control slurry rheology at higher solids content, allowing to operate safer with less water

Rheology modifiers for thickener optimization
Tailing ponds
Existing tailing ponds have limited lifetime with often lengthy authorization to be replaced or expanded. New environmental regulation are implemented to access best available techniques to control environmental impacts and remediation costs.
Opale™ Solution rheology modifier could be added into existing tailings disposal line to increase yield stress and beach slope angle at the deposition area.
