What Is Cyanide Leaching Dasen Mining

Cyanide leaching is one of the main gold processing methods, which can be divided into agitation cyanide leaching and percolation cyanide leaching. Among them, the agitation cyanide leaching process mainly includes the cyanidation-zinc replacement process (CCD method and CCF method) and unfiltered carbon cyanide slurry process (CIP method and CIL method).

Gold Cil Cip Gold Leaching Process Explained Ccd

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and
