Gold Processing Equipment like the IGR500 focuses on the recovery of the Fine Gold. The

Elution Wikipedia

Elution then is the process of removing analytes from the adsorbent by running a solvent, called an "eluent" past the adsorbent/analyte complex. As the solvent molecules "elute" 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
