  • AARL Carbon Stripping System Operation: Elution

    The use of this type of pump should make the continuous elution process competitive in smaller sized plants, possibly down to one tonne per day plants or smaller. A one tonne per day column would be approximately 300 mm diameter by 5 metres tall. The circuit shown in Figure 4 has the following advantages over that shown in Figure 3 and may become the preferred process. The carbon pump

  • 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. Loaded carbon is removed from the CIL circuit and the gold

    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 in its place. After the solvent molecules displace
