gold heap leaching in the netherlands

Open pit mining and loading of the heap leach facilities will be completed in Q2 of 2031. The constructed primary heap leach pad (HLP) will accommodate up to 90 M t of ore and is located approximately 1.2 km north of the Eagle Zone orebody, in the Ann Gulch valley. Ore above 0.30 g/t from the Eagle pit is sent to a three-stage crushing plant.

    Much thought and design goes into the making of a heap leach, to derive the best, most economical solution for recovering the gold from the ore. Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution.
