Here, the material is pumped to a processing plant to extract the gold. "This operation is much more cost-effective compared to a truck and shovel operation, due to the use of slurry transport. However, the majority of the tailings are stored together with process water, which makes hydraulic monitoring of dry heaps impossible."
