Lime and sodium cyanide are added to the tank, and compressed air is passed into the tank for leaching and adsorption. The activated carbon is added to the fully leaching slurry, and the activated carbon adsorbed the gold in the cyanide slurry and became the gold-bearing carbon. The leaching time is generally 24 hours to 48 hours.
