Gold occurs in ores in many different forms and the scheme of treatment has to be worked out accordingly. Fine, free and clean gold presents no problem provided that the cyanide solution contains no detrimental impurities. Coarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated ...

There were two general cyanidation flowsheets; sand leaching and all sliming. The latter ultimately has almost completely replaced sand leaching. With the advent of flotation and the fact that gold either free or finely disseminated in pyrite, etc., could be floated, many possibilities opened up for the treatment and concentration of …

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 ...
