  • 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.
