foam flotation for copper recovery

Selective recovery of copper from ammoniacal

2021-4-29  Under optimised conditions 86% of Zn and 75% copper were extracted from the microwave-roasted material. From the generated pregnant leach solution, it was possible to selectively separate 85% of copper to the foam phase by ion flotation, with sodium dodecyl sulfate (SDS) surfactant, as colloidal copper(II) tetraamine dodecyl sulfate.
