After completion of the leaching process (within months to years), the leached ore is either left in place, or removed to a disposal site, and new ore is placed on the leach pad (so-called on/off scheme, or dynamic heap leaching). During leaching, the piles present a hazard because of release of dust, radon gas and leaching liquid.
The chemistry involved in the dissolution of gold in the heap-leach cya- nidation treatment is the same as that for the agitation-cyanidation process. In heap leaching, the oxygen, essential for the dissolution of gold, is intro- duced into the cyanide solution as it is being sprinkled upon the ore heap.

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m high, 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3.

· This process has been successfully applied in practice in a variety of climatic conditions in regions such as the South American Andes, the Arctic, and tropical regions. Heap bioleaching has performed well in the subarctic zone, where the average annual temperature is 1.3 C [9,10]. Polymetallic ore from the Talvivaara deposit was processed
· This is a hydrometallurgical process in which the solution is applied for the dissolution of minerals from the ore that is used for the extraction of metals. Originally, heap leaching was practised 500 years ago. Georgius Agricola published a book De Re Metallica in 1557 and reported that the heap leaching process was finished in a 40-day cycle.
Gold Mine Heap Leaching Process. Crushed by jaw crushers and cone crushers to a certain particle size (30-50mm), raw ore is directly sent for heaping or granulated (to make finer particles agglomerate into coarse powder), and then transported to the ore heap site for heap construction. On the laid ore heap site, the heap system is set up.
The Heap-Leach Process Briefly stated, gold heap leaching is a hydrometallurgical process designed to treat amenable low-grade gold ores that contain roughly 0.5 gram per metric ton (g/t) gold to 1.5 g/t gold (Marsden and House, 2006; Wong Wai Leong and Mujumdar, 2010). The ore is stacked by various types of equipment
Gold Leaching( carbon in leach) process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as well.Gold Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high-grade silver.
· Hycroft expects to mine and stockpile at least 300,000 tons (272,155 t) of sulphide ore in 2021 that, once sufficient additional work on the novel process has been completed, will be available for testing to further refine operating parameters and measure its performance for large scale application of the oxidation heap leach.
The leaching solution of gold ore heap leaching is highly toxic cyanide containing solution. The cyanide concentration can reach to 1000 mg/l as the highest, which is generally maintained at 300-800 mg/l. The final concentration will also reach 200 mg/l, and the lowest concentration will also reach tens of mg/l.
