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 .
concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-designed and operated plants. This represents a gold recovery of 90–99% depending on the tenor of the feed solution. These high recoveries are achieved because the carbon is

Any experienced gold miner will tell you that the secret to recovering the most gold is to process a lot of material quickly— and a highbanker does just that! A high banker, also called a power sluice, is a piece of equipment that uses a pump to force water through a sluice to mimic the natural flow of a stream.

During the rush to the gold fields of the 1800s, a LOT of gold was removed from the rivers and banks of the Western US and Alaska. The old-timers used very ineffective methods, but a lot of gold was taken out of the streams and banks. That gold had been setting there for hundreds if not thousands of years.

Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time, 1890, the Author said "There is, of course, nothing for us to learn from this imperfect and rudimentary gold-extraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt ...
The mill jig installation is usually a compromise between gold recovery and available space limitations. Although it is depended upon primarily for the removal of only the relatively coarse values, a 60 to 70 per cent recovery of the total free gold values at the usual mill grind is not at all unusual.
Oct 20, 2014· Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Well, sulfides, selenides and tellurides are simply minerals which contain sulfur, selenium, and tellurium combined with some metal. Unusually this is the metal we are interested in, but sometimes other valuable metals can be mixed in as trace elements. An example of this is when gold occurs disbursed through a crystal of pyrite.
Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.
