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.
