    The classic method of recovery of gold and silver from cyanide solution was Merrill Crowe until the introduction of Carbon In Pulp (CIP) in the 1970's. The CIP process indicated savings in CAPEX.

    Carbon in pulp（CIP）is one of the methods of gold extraction by cyanidation.It is the process of gold cyanide for carbon adsorption after the cyanide leaching of gold-containing materials is completed. In actual production, most CIP plants will encounter various problems, which not only affect the normal operation of gold beneficiation, also seriously damage the economic benefits of CIP plants.

  • US5023060A - Recovery of gold by a carbon-in-pulp process ...

    A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

    Introduction. The well-known carbon-in-pulp (CIP) and carbon-in-leach (CIL) gold recovery processes are fairly robust. Considering the constantly changing characteristics of run-of-mine (ROM) ore, a robust process is in general a great advantage for a mineral processing plant. The disadvantage, however, is that because less input is required ...

  • Activated Carbon in Gold Cyanidation

    Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.
