CIL plant process flowsheet

Technical process introduction

 

Cyaniding carbon adsorption gold extraction process(Carbon In Leaching) has become an important method in gold cyanide extraction. The basic principle is that activated carbon can adsorb liquid gold in alkaline cyanide solution. With the desorption of gold-bearing carbon and the regeneration of degold-bearing carbon gradually mature, activated carbon can be recycled. CIL process has become the main method of gold extraction and has been rapidly promoted, giving full play to the advantages of less investment ,lower cost of carbon pulp process and being able to process low-grade gold ore.
