A disadvantage that follows the increasing concentration of carbon in slurry is the high amount of carbon fines. The amount of fines formed in the process is proportional to the carbon present in the system. With 8 kg/m 3 of carbon, the loss of carbon fines is 3.09 kg/h, which escalates to approximately 15 kg/h for 40 kg/m 3 of carbon. This ...

stirred tanks. Freshly activated carbon, with a much larger particle size than the ore, is introduced into the final tank. Typically the carbon is retained in any tank by suitable screens and is intermittently progressed up the bank by some type of gentle pumping system and is finally removed from the slurry for desorption of the values.
CIL process is widely used in the mining industry and in particular, it is an integral part of gold extraction plant. It is a continuous process in which gold is recovered by cyanide leaching of ore slurry and simultaneous adsorption on activated carbon in agitated tanks (Figure 1).From the time CIL process was introduced in the gold processing, a lot of progress and …
