Gold and silver are extracted from dilute or low-grade ores containing a high percentage of impurity by a hydro metallurgical process called cyanidation. In this process, cyanide is converted to a water-soluble complex of metal-cyanide, which is then precipitated using activated carbon, zinc dust, or ion-exchange resins.
