Elution
Elution then is the process of removing analytes from the adsorbent by running a solvent, called an quot;eluentquot;, past the adsorbent/analyte complex. As the solvent molecules quot;elutequot;, or travel down through the chromatography column, they can either pass by the adsorbent/analyte complex or they can displace the analyte by binding to the adsorbent

Elution
EluentIn analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ionexchange resins to remove captured ions.
In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or quot;bound toquot;, an adsorbent in a liquid chromatography column. The adsorbent, a solid phase (stationary phase), is a powder which is coated onto a solid support. Based on an adsorbent's composition, it can have varying

carbon. The filtrate is then sent to the elution vessel, V401, where the elution process begins. The gold is eluted into a water solution from the carbon by the AmericanAnglo Research Laboratories (AARL) method, leaving the barren carbon behind. Figure 5 shows the carbon adsorption and AARL elution processes. The loaded eluant, Stream 37,
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 (lt;100 g/t) to be reactivated and returned to

Carbon in pulp
Loading gold into carbonCarbon in pulp (CIP) 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 competing silver or copper does not prohibit its use.
Electrowinning and Smelting Resource Book
Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.

Elution an overview ScienceDirect Topics
Elution of AM2B 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.
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.

Extracting Gold HowStuffWorks
Removing the goldbearing 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 rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
