As a matter of fact a sart plant can reduce the operational cost and increase the incomes in a gold mine although the main achievement is to make feasible the treatment of a gold-copper ore deposit.
Be leached in 24 hours in a conventional agitated leach process. gold recovery is typically 70 as compared with 90 in an agitated leach plant. even with this inferior performance the process has found wide favor due to the vastly reduced processing costs compared with agitated leaching. the cost advantage areas are largely as follows:
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.
Carbon as a media of recovery for gold from leach solutions did not gain wide acceptance in the gold industry until the 1970's with the explosion of heap leaching of vast quantities of low grade gold ores and subsequent production of many gallons of pregnant leach solution.

Concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-designed and operated plants. this represents a gold recovery of 90–99 depending on the tenor of the feed solution. these high recoveries are achieved because the carbon is

Gold rich veins are restricted to the proterozoic rocks which consist of biotite-feldspar-quartz and quartz-feldspar gneisses of sedimentary and plutonic origin. the hydrothermal system is structurally controlled and the higher grade mineralization occurs in quartz-sulfide veins filling tensional fractures.
Heap leaching technique in mining within the context of best available techniques bat caner zanbak phd supported by euromines – the european association of mining industries metal ores amp; industrial minerals november 2012
Heap leaching: in the open cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. the cyanide dissolves the gold from the ore into the solution as it trickles through the heap. the pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
In most cases gold processing with cyanide leaching usually with carbon adsorption is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet selection and cost drivers and get the best out of the process.
Jan 01 2016 the recent development of a thiosulfate leaching plant at barrick gold's goldstrike operation has alluded to the complex and unstable nature of leaching gold using this system and the significant process design difference of using thiosulfate over conventional cyanide braul 2013 choi et al. 2013 la brooy and smith 2013.

Leaching and absorption are simultaneous is the most outstanding feature of cil process. generally cil has 6-10 stages of tanks. the sodium cyanideor some other leaching reagent solution is added into the first tank and gold starts to be leached most cil plant will add the activated carbon from the second tank to the last one.
Leaching gold from sulfide ores is difficult at best. generally the recovery for cyanide leaching of sulfide or refractory ores is no better than 30 which is not a worthwhile venture. the use of alkalies such as calcium oxide will prevent the decomposition of cyanide in solution to form hydrogen cyanide gas.
Model since gold is leaching from the ore into solution at the same time as it is adsorbing onto the carbon and the concentration of gold in solution in each stage which is still assumed to be ...
