Cost competitive process for metals recovery


Customer: Ekokem Co.


Selective recovery of copper and zinc from pregnant leach solution.

  • 4 possible recovery process technologies were evaluated and tested in VTT laboratories using hydrometallurgical Flexmet platform.
  • According to the laboratory experiments, the most promising technology, hydroxide precipitation, was selected for preliminary techno-economical evaluation with HSC Sim software.

Selective, safe and cost competitive process for metals recovery was found based on laboratory experiments and techno-economical evaluation.
