Carbon Adsorption In Recovery Of 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. This assures a rapid interface between the carbon and the gold loaded cyanide solution. charged with activated carbon. The minimum load

DESORPTION OF GOLD AND SILVER FROM ACTIVATED CARBON

used in the leaching of gold from the ore. Such a process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen. The common processes for recovery of the gold solution include carbon adsorption, Merrill Crowe process, electrowinning and ion exchange/solvent extraction. Activated

Elution and Carbon Reactivation Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

The leaching and adsorption behaviour of gold ores

adsorption 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.

Leaching and adsorption circuits for better metal extraction

In CIL, adsorption of gold and silver onto activated carbon is also completed in agitated tanks with interstage screens used to retain the activated carbon within the tank. The sizing of the tanks is calculated based on the time required to completely leach the ore, usually 24 72 hours.

The leaching and adsorption behaviour of gold ores

Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg robbing at the ore surface. A variable order empirical model of the Mintek form was used to describe leaching, while adsorption was modelled using the film transfer model. A model of this form was also used for preg robbing using the
