Реферат: ION EXCHANGE TREATMENT OF ZINC VALUES ABSTRACT OF THE DISCLOSURE Zinc values are leached or converted in a solution con-taining excess SO2 or HSO3-ions, selectively extracted from that solution into an organic phase containing organo acid phosphates and-stripped from the organic phase for further processing.
Zinc recovery process comprising recovering zinc values from an acidic solution containing hydrocyanic acid, the zinc being recovered as complex zinc cyanide anions, use of the above method for copper recovery
