Processing Heap Leachable Gold Ore byCyanidationOxide ore low grades will be unloaded on the heap leach PAD. Lime must be added during the discharge in order to control pH. Harvesting must be performed after the ore discharge is completed in order to avoid compaction caused by the trucks during the leach cell construction.

The pregnant solution is collected in the operations pond and then pumped to the Carbon in Columns Plant CIC where gold and silver are adsorbed on activated carbon. The gold and silver and then eluted at high temperature and pressure, using a cyanide and caustic soda solution. The result is a more concentrated solution of Au and Ag, which is sent to Merrill Crowe process plant MC.
