Product Description
Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to a degree of 99%. It is the first choice of modern gold mining and gold beneficiation plant.

It mainly include following equipment: 
Jaw crusher, Ball mill,Vibrating screen,Spiral classifer,Belt conveyors,Hydrocyclone,Thickener,Leaching Tanks,Electrowinning and desorption device,Gold smelting furnace and so on.
 
 
Application:
 
CIL mainly applies for the process of above 1g/t grade gold ore and gold ore with large bearing ore volume: silver, platinum, copper, etc. As CIL sees a better performance in extracting these minerals at the same time. And Hongji Mineral Dressing Test Center can help you with the component testing of your ores.

Feature
●     1. After the crushing and grinding stage, add 9 step-arranged high-efficiency cyanidation leaching tanks into the pulp. Gold pulp cyanidation is carried on the first two leaching tanks, countercurrent adsorption operation is carried on the last six or seven leaching tanks (cyanidation and adding activated carbon simultaneously).
 
●     2. In the adding activated carbon step, add the coconut shell activated carbon (small hole, high activity, wear-resisting and renewable) specially selected by Hongji mineral processing design institute into the pulp, which can dissolve and adsorb the gold and silver ions then form the gold loaded carbon according to the characteristics of gold and silver adsorption.
Compared with the traditional gold extraction process, Hongji gold CIL process ensures the gold and silver dissolution and the adsorption of activated carbon synchronously, which will not be affected by the excessive ion concentration, greatly improves the recovery rate of the precious metals (such as silver and copper) in the associated metals , and significantly improves the economic benefits.
 
●     3. Vibrating screen and dewatering screen are the key equipment for the reverse movement of pulp and carbon. Filter press and high frequency dewatering screen developed by Hongji can effectively reduce the carbon wear on the surface of vibrating screen and in the process of continuous slurry pumping, and reduce the cost, facilitate the maintenance and operation.
Air lifter used in the agitation process can make the slurry carry on small minor-cycle. Hongji air lifter greatly reduces the power consumption by 70%, and make the solid materials suspend uniformly, the wear of activated carbon is small, and the recovery of gold is high, which is an important equipment in the modern gold cyanide plant.
 
●     4. Hongji desorption electrolysis system implements high-temperature desorption electrolysis on gold in the gold-loaded carbon through the mixed liquor of sodium cyanide and sodium hydroxide. After wood chips and other sundries are removed by washing machine, and the gold desorption is carried out by Hongji high-temperature and high-pressure desorption method (150 degrees and 0.5Mpa), which can resolve 99% of gold within 2-6 hours.
