【Introduction】: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.
【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 Xinhai Mineral Dressing Test Center can help you with the component testing of your ores.

Gold Leaching Process
---Process Description
|
|
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 Xinhai 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.
|
|
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 Xinhai 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.
|
|
4. Xinhai 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 Xinhai high-temperature and high-pressure desorption method (150 degrees and 0.5Mpa), which can resolve 99% of gold within 2-6 hours.
