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 CFC Mineral Dressing Test Center can help you with the component testing of your ores.
After Crushing and Comminution, add the gold ore slurry into 9 Leaching Agitation Tanks, pour in cyanide solution in the first 2 tanks and Activated Carbon in the following 7 tanks for the reverse-absorption process–This design shortens the time period of gold staying in the cyanide pregnant solution and recovers gold in advance, which sees a faster investment return compared to other designs.
Filter Press and Vibrating Screen is needed in gold ore slurry reverse-transmission process.
CFC has a design that ensures the minimum carbon gold loses during transmission. It lower the gold loses and the processing line is easy to maintain.
After the carbon leaching and Elution of gold, NaCN and NaOH solution is used for removing the gold from loaded carbon at a high temperature. Then the loaded solution passes through the electro winning cell and the metals are attached to cathodes.
Desorption Electrolysis System
CFC Desorption Electrolysis System can successfully aggregate these steps in one processing unit, the pure gold and other useful metals are highly attained via this system.
