Innovative solutions for sustainable Metal Ore processing

Optimize metal ore processing by integrating cutting-edge technologies for greater efficiency and minimal environmental impact with our following innovative solutions : 

 

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

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
 

Key benefits

  • Rheology control

  • Water and energy savings

  • Significant productivity increase

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.


Key benefits

  • Rheology control

  • Improved pond shelf life

  • Safety improvement

  • Risk management : Liquid tailings & dam collapse

  • Sustainability: controlled footprint

Filtration

By improving the slurry state of dispersion, Opale™ solutions technology greatly improve filtration and dewatering yield
The metal particles inside the ore slurry are properly spaced and such conditioning after the thickening step improve filtration process / conditions.

 

Key benefits

  • Filtration time reduced
  • Filtration rate increased
  • Moisture content achieved
