Elution - Wikipedia

In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions. In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or "bound to", an adsorbent in a liquid chromatography column ...

Electrowinning - an overview | ScienceDirect Topics

Operation of the electrowinning process differs depending on the elution procedure that is used. In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough (<100 g/t) to be reactivated and returned to ...

Parameters affecting gold elution using the AARL process are reviewed and critically analyzed in an attempt to optimise metallurgical efficiency and minimise costs in both current and future carbon adsorption operations. Such factors as acid washing, column geometry, elution temperatures and pretreatment reagents are discussed together with eluant water quality and eluate flowrates.

Carbon regeneration -

The absorptive properties of activated carbon are due to the micro-porous structure of each grain resulting into large surface area per unit column of carbon. In the gold industry, activated carbon is utilized in CIP/ CIL process to transfer dissolved gold from cyanide leached slurry to elution column where gold is desorbed from the carbon.

ACTIVATED CARBON IN GOLD RECOVERY

the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that affect the adsorption of gold are discussed. Finally, performance monitoring methods that help control the operation of the CIP/CIL process are discussed. 2.

Elution and Carbon Reactivation - Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. 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.

Carbon and Resin Technologies for Gold Recovery | Mining | SGS

Carbon-in-columns During this process, the cyanide leaching solution passes through columns filled with ore. The process is highly effective for removing gold from low grade ore. Resin Recovery Technologies Resin RIL (Resin-in-leach)/RIP (Resin-in pulp) In recent years, resin is replacing carbon as the gold recovery substrate of choice.

sent to the carbon columns, CIC-401, via Stream 29. Gold is adsorbed onto the activated carbon. The filtrate is then sent to the elution vessel, V-401, where the elution process begins. The gold is eluted into a water solution from the carbon by the American-Anglo Research Laboratories (AARL) method, leaving the barren carbon behind. Figure 5
