Two primary methods, Carbon In Pulp (CIP) and Carbon Columns probably comprise the most widely utilized techniques for extracting gold, now days. In CIP, the carbon is mixed with the cyanide leach solution, and agitated in the leach tanks, and agitated with the ore while the gold is being dissolved.
Read MoreAnswer: CIL is carbon-in-leach and CIP is carbon-in-pulp. The difference is that activated carbon is in every tank where gold is leached from an ore slurry with cyanide while CIP has separate tanks for just leaching and then for absorption to activated carbon. The costs of the two options will v...
Read Moreadsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it is shown that a variety of metal-cyanide species can be used to leach gold from certain refractory ores.
Read MoreCarbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that

Read MoreThe 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. This meant that lower grade ores could be economically treated than otherwise would have been the case. Soluble losses from CIP plants are lower than Merrill Crowe and the process is less vulnerable ...
Read MoreCarbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. In the absorption stage, this solution flows through several agitation tanks containing activated carbon.

Read MoreA 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.
Read MoreCarbon-in-pulp (CIP) and carbon-in-leach (CIL) technology is applied successfully to recover gold from cyanided pulps. These plants are operated on a counter-current basis allowing for small concentrations of gold to be recovered at the expense of inefficiencies such as back-mixing, additional carbon breakage by interstage pumps and difficulties in carbon inventory management.
Read MoreActivated carbon is widely used for gold recovery from cyanide leach liquors via carbon-in-leach (CIL) or carbon-in-pulp (CIP) technology. From all the base metals cyanide complexes typically present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded onto activated carbon…

Read MoreIn the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank.
