  • Technical Report Treatment Of Cyanide Heap Leach And Tailings

    CYANIDE LEACHING Cyanidation uses solutions of sodium or potassium cyanide as lixiviants (leaching agents) to extract precious metals from ore. Cyanidation techniques used in the gold industry today include heap or valley fill leaching, agitation leaching followed by carbon in pulp (CIP), and agitated carbon in leach (CIL).
