major steps of gold process in elution plant

THE ADSORPTION AND ELUTION OF PLATINUM GROUP …

using an analogue of the AARL process was investigated. Platinum and palladium elute from activated carbon almost to completion in 4 to 5 bed volumes at 80°C, while the elution of gold at this temperature is slow, with a significant amount of gold still to be eluted after 16 bed volumes.

Elution and Carbon Reactivation - Resource book. During the CIL process, gold is leached from the an The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

AARL ELUTION PROCESS PDF - sevrunn.com

The process is fully automated and controlled by electronic sequence controllers which switch both pumps and valves for each step. By this time most of the gold and silver on the carbon will have been desorbed into solution and both the carbon and the solution will have reached an optimum temperature for procesw subsequent elution proper.

The process design of gold leaching and carbon-in-pulp ...

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). The reagent and utilities operating costs associated with leaching, adsorption, elution and ...

The elution step may be further divided into two major stages; carbon preheat and elution proper. Here a separate column is provided for acid washing. The advantages of this are dubious in that there would be more than enough time in a twenty four hour period for both steps …

Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver. 6. Elution & Electrowinning The loaded carbon is fed into an elution column where the bullion is washed off. The barren carbon is recycled.

Higher cyanide concentration in the pre-treatment step results in more efficient elution up to a ... processes have been the main commercial processes on almost every gold plant built since 1980 (Fleming, 1992; Van Deventer, 1984). ... two major steps of the process, i.e. the adsorption and elution sections, were investigated and ...

the process of gold elution - AnnaSweetHome

the process of gold elution. Carbon in pulp is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process Introduced in the early 1980s Carbon in Pulp is regarded as a simple and cheap process As such it is used in most industrial applications where the presence of ...

Elution - an overview | ScienceDirect Topics

Elution of AM-2B resin is similar to that of Minix; but a longer elution time seems to be required (Bolinsky and Shirley, 1996).The process includes a series of elutions, contacting the loaded resin with different solutions. The elution flowsheet differs from plant to plant, and some of the steps described below are optional.

Production of Gold

Unit 400 – Carbon Adsorption and Elution The adsorption of gold from the pregnant leach solution onto the activated carbon is the key step in the recovery process. This recovery begins when the leach filtrate is sent to the carbon columns, CIC-401, via Stream 29. Gold is adsorbed onto the activated carbon.
