Leaching Adsorption Resource Book

Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material. Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold.
