Gold Recovery Process Watercare Innovations

Gold Recovery Process. Recover additional value from a gold plant. Fine carbon, loaded with gold, is generated from both the absorption circuit and elution circuits during the Carbon In Pulp (CIP) or Carbon In Leach (CIL) mineral recovery process. The fine carbon, once recovered, cannot be re-introduced into the process plant, and is consequently often a waste stream.
