English

Subject field(s)
  • Mining Equipment and Tools
  • Metals Mining
  • Ore Extraction and Transport
  • Water Resources Management
CONT

A series of storage ponds are required to manage the heap leach solution associated with the heap leach process; these include : pregnant solution pond; barren solution pond; [and] event pond. The pregnant and barren ponds are lined storage ponds for the solutions that will be used throughout the heap leach process. The event pond will be used to collect overflow from the heap leach pad during precipitation events. These ponds are sized to handle the 100-year rain event for 24 hours. These ponds will be lined to reduce the potential environmental impacts, and measures will be implemented to prevent access by wildlife.

CONT

Heap leaching is often the most cost-effective way to extract value from gold or copper ores. Heap leaching involves placing ore-grade material on an impermeable liner foundation with a solution collection system of drainpipes and irrigating the surface with either cyanide solution(for gold) or acid(for copper). Within the heap, chemical reactions occur which liberate the payable metal from the rock. The resultant solution, called pregnant leach solution(PLS), reaches the liner and the collection pipes, and then reports to a storage facility(pond) for processing where the metal is removed, the solution conditioned, and re-applied to the HLP [heap leach pad] as barren leach solution(BLS).
