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%. View details

Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold-containing solution is leached. Then used the method of carbon adsorption, zinc powder displacement device and so on to separate gold from the liquid.
Heap leaching method is always used for low-grade ore, small gold mine, or both. These ore can not to process by using the conventional method.
The heap leaching plant adapt to local condition. According to the feature of the landscape, we can built permanent heap plant or overlap-type heap plant. If the slope was not steep with open views, permanent heap plant is suitable.
The raw ore is crushed into fine particles (30-50mm) by using jaw crusher or cone crusher produced by Xinhai, then will be heap leaching directly; or pelletization (fine particles are pelletized into bigger lumps ), then piled by forklift.
Then the large piles will be sprayed by the leaching solutions, through which the gold-containing solution will be leached from the piles. The pregnant liquid will flow into pregnant solution pool. Then used the method of carbon adsorption, zinc powder displacement device and so on to separate gold from the liquid. The tail liquid will be recycled.
The video is desorption electrolysis system of Xinhai Tanzania gold project. Desorption electrolysis system is one of the key decive in CIP. In gold electrowinning process, when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au（CN）2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.
