Option 1 the heap leach pads would be covered with either a 5-foot engineered evapotranspiration ET alluvial cap; Closure Option 2 would consist of an engineered synthetic liner with an ET alluvial cap. At the early stages of closure the draindown would be managed by active evaporation at the top of the copper heap leach pads using evaporators.

Apr 25 2018 Heap leaching is used to extract gold copper silver uranium and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s and then by several gold mines in the western parts of the US a few years later. Since then heap leaching has been adopted successfully by many mines across the world.
