extracted. The barren solution is then reapplied to the top of the stack. Overall, gold recovery using heap leaching generally ranges from about 50 to 90 percent, although this percentage depends on many variables (Kappes, 2002; Marsden and House, 2006). Figure 1 is a simplified flow diagram of the gold heapleach process.

Inclusion of heap leach metal recovery detail.
In 2011 leaching, both heap leaching and insitu leaching, produced million metric tons of copper, 22 percent of world production. The largest copper heap leach operations are in Chile, Peru, and the southwestern United States. Although heap leaching is a low costprocess, it normally has recovery .
gold extraction plants. In the carboninpulp process adsorption occurs after the leaching cascade section of the plant, and in the carboninleach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery

Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.
