For heap leaching to be feasible, the ore must be porous and permeable to the leaching solution. Since the ore is not finely ground, the cyanide ions must diffuse through the host rock to dissolve a gold particle. The dissolved gold must diffuse out ward. This gives leaching cycles varying from weeks to
The process was developed for the pre treatment of refractory concentrates ahead of conventional cyanide leaching for gold recovery. As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is prevented from being leached by cyanide.

ore body at Gedabek is a complex copper gold porphyry deposit. Ore from the Gedabek mine, which initially was mainly oxidic in nature, was treated by cyanide heap leaching to produce a pregnant leach liquor, from which gold was extracted by fixed bed resin ion exchange. Resin ion exchange was used at
With the rising gold prices in recent years, it further stimulated the rapid development of gold industry. As the exhaustion of high grade gold ore, researching on middle low grade and refractory gold ore and strengthen the traditional gold mining process undoubtedly have become the main trend in global gold beneficiation industry.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
Cyanidation and concentration of gold and silver ores. Factors affecting Thickening rates. As discussed in Chap. II, a number of chemical and physical factors affect the settling rate of ore particles suspended in water or cyanide solution. The use of lime and caustic starch has been mentioned.
it joins the overflow from the leach thickener. Water from this tank is pumped to the grinding circuit where it is mixed with fresh ore by adding it to the SAG mill and ball mill feeds.
