Heap leaching facilitates the profitable extraction of gold from very low grade ore. Prior to heap leaching, either run of mine (ROM) or crushed ore is heaped into structures 10 to 20m high that are stacked on an impermeable layer. A dilute cyanide solution is sprayed on the heap, percolates through the pile and dissolves the available gold.

Heap leaching for cooper, gold & silver mines in combination with MegaStand™ and flexible pipes: FlexNet™. MegaStand™ is the ultimate solution for overhead irrigation of leaching pads and is made from acid resisting materials making it suitable for multiple leaching of minerals.

North Lanut has been in operation since 2004 and is the longest serving heap leach mine in Indonesia. The project has been a model mine for training national mining engineers. Lanut previously utilized a static heap leach approach for high sulphidation, epithermal, low-grade oxide ores but many pads have now been retreated to improve recovery.

16-10-2020· There are several ways to extract rare earth metals from their carrier minerals, such as direct leaching using sulfuric acid at temperatures of 155–230°C, alkali cracking using a sodium hydroxide solution at 140°C, roasting using sodium carbonate at 900°C, and alkaline fusion using flakes of sodium hydroxide at 400–500°C.

Brookmount is utilising heap leaching technology as a low environmental impact form of gold mining in its Indonesian production. Gold can be extracted through excavation of ore instead of the more destructive and expensive shaft mining. Brookmount is sensitive both to its environmental footprint and its positive impact to local communities.

Heap leaching & SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.
