Gold leaching carbon in leach process is widely used in the newly built gold leaching plants in recent years and a lot of plants are changing into cil as well gold leaching cil process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content it is unsuitable for the gold ore with highgrade silver
Gold carbon in leach plants updated january 2017 gold processing plant carbon in leach cil plant a carbon in leach gold recovery plant this plant processes 4 million tons of ore per year with an average gold content of 0043 ounces of gold per ton of ore approximately 85 of the gold is recovered in the plant
The process design of gold leaching and carboninpulp circuits contaminants these are removed by thermal regeneration of the eluted carbon typically in a rotary kiln at temperatures of 650750176c regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation the eluted and regenerated carbon is screened at about
Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution the solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon and it is called carboninleaching process cil heap leaching is always the first choice to process low grade ore easy to leaching
Gold plant will be that of the leaching and carboninpulp circuit cip the reagent and utilities operating costs associated with leaching adsorption elution and regeneration would typically make up some 15 of total operating cost whilst the capital costs

Two primary methods carbon in pulp cip and carbon columns probably comprise the most widely utilized techniques for extracting gold now days in cip the carbon is mixed with the cyanide leach solution and agitated in the leach tanks and agitated with the ore while the gold is being dissolved
Cil carbon in leach process is the most efficient method to leaching and recovering gold from gold ore the most protruding features is that leaching and adsorption are carried out at the same time which greatly saves the cost of construction and operation it has become the first choice of modern gold mining and processing plant design
Gold cil amp cip gold leaching process explained ccd carbonin 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 pregrobbing materials such as natural absorptive carbon
Gold extraction plants in the carboninpulp process adsorption occurs after the leaching cascade section of the plant and in the carboninleach process leaching and adsorption occur simultaneously in both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery
This batch model was extended to a continuous model that simulated three leaching and seven carboninleach tanks the effect of processing the oxide and sulphide ores studied was examined and the model shown to satisfactorily describe the extraction of gold from the telfer oxide ore a sensitivity analysis of the effect of process changes
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 leaching plant design mineral processing metallurgy
