In 1970s , with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold , make recycle the carbon and reduce the cost , and easy to process the gold ...
CIL plant mainly applies for the process of above 1.0gt grade gold ore. The gold CIL process is mainly used in the oxide ore, which has low grade of silver. Download Gold CIL Plant Design File here. OPERATION amp PROCESS DESIGN. CIL gold leaching process mainly include Impurity removal , condense before leaching , leaching and adsorption ...
Nov 01, 2020 In the carbon-in-leach test CIL-1, the observed gold recovery from solution onto activated carbon was 96, while holistic recovery of gold remained only at 62. However, in the longer carbon-in-leach test 36 h, CIL-2 holistic gold recovery of 77 was obtained, whereas the gold uptake from the loaded solution was at the same level i.e. 95.
Process Description 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 processThis design shortens the time period of gold staying in the cyanide pregnant solution and recovers gold in advance, which sees a faster investment ...

Jan 02, 2013 Carbon-in leach CIL is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon. Simultaneous leaching and absorption help minimize the problem. CIP-CIL versus Agitated Tank Leaching.
Apr 11, 2018 Gold Leaching carbon in leach was developed from CIP Carbon In Pulp, is characterized by less process flow, timesaver in the leaching process, thus reducing the production expenditure. Besides, advanced extraction technology improving the efficiency of gold extraction. The CIL production line is wider use than CIP in the mineral industry.

The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650750 C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened at about
Carbon-in-columns During this process, the cyanide leaching solution passes through columns filled with ore. The process is highly effective for removing gold from low grade ore. Resin Recovery Technologies Resin RIL Resin-in-leachRIP Resin-in pulp In recent years, resin is replacing carbon as the gold recovery substrate of choice.
Gold CIP Production Line. Process Introduction. CIP Carbon in pulp process is a high efficient method to leaching and recovering gold from gold ore, The most different from CIL process is in CIP process, gold leaching and adsorption are separated, first leaching, and then adsorption.
