Gold CIL leaching process is an efficient method for extracting and recovering gold from rock gold and gold tailings. By adding activated carbon to the slurry and simultaneously leaching and adsorbing gold, it include leaching pulp preparation, cyanide leaching, activated carbon adsorption, the electric shock to get gold mud, to take off the gold charcoal recirculation, leaching slurry ...

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 adsorption take place in the same tanks.

There is a lot of interest these days in processing the tailings dump from past hard-rock mines. ... Small gold attached to matrix in and around a mill site can be found by the diligent observer. Some of it is large enough to be detected with a metal detector some requires a very keen observer. Small micro mount specimens of gold may have very ...
