Rock that is not economical to process is stored in overburden rock storage areas. Heap leaching is used when the ore contains a lower grade of mineral content. We then “strip” the gold from the carbon by washing it with a caustic cyanide bottom and the water can be returned to the plant to be reused in processing.
