We have solved the primary mine water treatment challenge: calcium sulfate scale.

Salt Splitter changes water chemistry from scaling to non-scaling. Achieve 96%+ recovery in a simple, chemical free, mine water treatment membrane system.

ElectroChem Advanced Electrodialysis can selectively remove “pollutants” or recover minerals of interest.

SaltMaker Evaporator Crystallizer can treat highly concentrated mining wastewaters to produce solids for true zero liquid discharge (ZLD).

Solutions for:

  • Tailings
  • Mine runoffs
  • Process waters
  • Selective recoveries
  • Improve yields

Benefit from:

  • Treat calcium sulfate (gypsum) or other multivalent pair saturated waters 
  • Treat mine runoff: mineral rock run off (MRR), acid rock drainage (ARD), acid mine drainage (AMD)
  • Tailings management: minimal pre-treatment, volume reduction, meet discharge requirements
  • Recover value from effluent
  • Simple, high recovery membrane system
  • Remove conventional scaling limits, no lime softening, extreme brine concentrations
  • No temperature sensitivity
  • No chemical inputs
  • Mobile pilot plants available


SaltMaker Evaporator Crystallizer

  • True zero liquid discharge (ZLD)
  • Produce freshwater and solids
  • Treat any concentrated wastewater with little to no pre-treatment
  • Modular design

ElectroChem Advanced Electrodialysis

  • Minimal pre-treatment
  • Packaged plant for remote operations
  • Remove all ions of concern

Salt Splitter

  • Extreme recoveries on previously scale limited waters

View case studies from multiple mining projects treating various wastewaters. ElectroChem Advanced Electrodialysis and Salt Splitter are a safe, reliable, temperature independent solution to treating tailings and mine runoffs without chemicals. Selectively recover minerals of interest and remove pollutants upstream to increase floatation yields while reducing your ponding liability.
