Heap leaching gold extraction does not have high requirements for topographic conditions. Permanent dump storage yards or superimposed storage yards can be set according to local conditions and topographic characteristics. If the mountain top and hillside are gentle and open, it should be used to build a permanent dump yard.
Heap leaching process composes of concrete of the site , pre-process of the ore (crush or produce ) , concrete heap , spray leaching , disinfect and discharge the recovery of gold from pregnant solution .
Raw ore treatment:
After crushing to a certain particle size (30-50mm) by jaw crusher and cone crusher, it will be directly dumped; Or carry out granulation treatment (agglomerate the finer particles into coarse powder particles), and then transport the ore to the ore pile by forklift for stacking.
Heap leaching system:
Heap leaching system shall be set on the laid ore heap. After the cyanide solution reacts with the ore heap, the gold containing solution (precious liquid) seeps from the bottom of the ore heap and flows into the precious liquid pool. It is pumped into the adsorption column by the precious liquid pump. The solution adsorbed by activated carbon is lean liquid, which is returned to the spray system for reuse.
Gold extraction from precious liquid:
High efficiency and low consumption quick desorption electrolysis system or zinc powder replacement device is used to extract gold from your liquid, and the product is obtained after smelting.
Main Machine：Jaw crusher ,Cone crusher,Spray device, Desorption, Electric separation,Smelting furnace.
The gold ore heap leaching process is often used to develop gold ore with small ore body or low grade, or both, but cannot be developed and utilized by conventional methods.
