PROCESS FOR EXTRACTION OF ION METALS OF CUPRUM SUBGROUP FROM PROCESS WASTES

摘要

A process for extraction of ion metals of cuprum subgroup from process wastes by passage through sorbent. Preliminary an electrochemical reduction stage of ion metals is carried out, providing the extraction of cuprum ions to concentration of 60 mg/dmwith further cation-exchange treatment to boundary permissible concentration (BPC) values, the extraction of silver ions to concentration of 4.5 mg/dmwith further treatment to BPC values.
