A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and
· Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon in pulp circuit (CIP).

Carbon In Pulp Technology For The Extraction Of Gold Pdf 2016-5-25 · tailored to gold recovery applications. DG activated carbon can enable the extraction of even trace amounts of gold from every ton of ore, even when processing average or low-grade ores.
· 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 carbon is added to ...
Extracting Gold HowStuffWorks23/02/2009 Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of
The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1

· The affinity of the activated carbon for the gold complexes is thus [Au (SC (NH2)2)2] + > [Au (CN)2] -. The ordering is the same as the order- ing of the relative rates of adsorption observed in the dynamic adsorption experiments. The n value for the gold (I) thiourea complex is indicative of a chemisorption process.
