GOLD CIL process technology
The so-called CIP generally refers to the following cyanide leaching is completed, then the process of carbon adsorption. The CIL leaching process is the rule and the adsorption process simultaneously. Both are adsorbed gold from the pulp, no essential difference. CIP is the only leach and adsorption in their respective grooves performed; and CIL leaching adsorption law is carried out in the same slot, this slot or groove called the CIL leach adsorption tank. In fact, in the CIL process, often the first one or two slots are not charcoal (called pre-cyanide), and therefore, there is no strict boundaries between the two, but less stirring tank CIL process the number of some of it .

A typical CIP process mainly, activated carbon adsorption by the cyanide leaching, desorption and regeneration of carbon and other major operations, whose characteristic is fresh (or regenerative) activated carbon adsorption tank was charged last, and the direction of movement of the carbon slurry the opposite direction of flow, and finally extract loaded carbon from the first adsorption tank, so called countercurrent carbon adsorption. Carbon adsorber front to back solution gold grade decreased from behind by the groove to mention loaded carbon grade is gradually increasing. Finally, by the first groove. Since countercurrent adsorption process this carbon pickling and thermal desorption regeneration fresh charcoal or charcoal, the most active, the fastest adsorption rate can make the final grade gold tail was reduced to a minimum and reduce the tail of gold has been dissolved opportunity fluid loss, thereby improving the adsorption rate.
