The process design of gold leaching and carbon-in-pulp ...
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 1 000–1 500. A portion of the loaded carbon is periodically removed from the first adsorption

Gold CIL & CIP Gold Leaching Process Explained CCD
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 …

nominal throughput of 500000, t/year through a hybrid carbon-in-leach (CIL) plant to recover gold as bullion. Sulphide ores will be treated at a nominal throughput of 250,000 t/year through a conventional froth flotation plant to produce a copper-gold concentrate. A block diagram showing the overall flow sheet is shown in Figure 1.

Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to a degree of 99%.
Carbon Adsorption In Recovery Of Gold - Mine Engineer.Com
The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.

Gold Processing Plant Carbon In Leach Cil Plant Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98%.
Gold Carbon In Leach Plant Updated January, 2017
A Carbon In Leach Gold Recovery Plant. This plant processes 4 million tons of ore per year with an average gold content of 0.043 ounces of gold per ton of ore. Approximately 85% of the gold is recovered in the plant.

Gold Cyanide Leaching Process - Outotec
Outotecs cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations.
Gold ore Carbon-In-Leaching (CIL) processing technology ...
The flotation tailings containing the unrecovered gold from the primary circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL).
