  • Leaching & Adsorption Resource Book

    Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.

              Granular Activated Carbon in Columns. The alternative method of treating a water (or air) stream is by passing the stream through a stationary bed of carbon. To limit head losses to a reasonable value, the particle size of the carbon is made larger. Accordingly, this is often called granular activated carbon (GAC).

            • Adsorption Wikipedia

              Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent), respectively.
