Gold recovery can become uneconomical when cyanide-soluble base metals such as copper and zinc are present in gold ore deposits. These metals form weak acid dissociable (WAD) complexes with the cyanide and preferentially competes for cyanide. The result is high cyanide consumption, poor gold doré purity and high concentrations of copper ...Web

Panning. Gold panning is mainly a manual gold separation technique from other materials. Large, shallow pans are filled with gold-containing sand and gravel. The pan is submerged and shaken in water, sorting the gravel gold and other material. It quickly settles down to the bottom of the pan as gold is much denser than rock.Web
