Gold is recovered through a carbon in-column system, followed by stripping of metal values from carbon, electrowinning and smelting to yield a doré (containing gold and silver) suitable for sale. Control of copper in leach solutions is undertaken in a sulfidization, acidification, recovery, and thickening ("SART") plant, which also regenerates cyanide.
