DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND CARBON

Abstract - Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In 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 ...

The process design of gold leaching and carbon-in-pulp circuits ... The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as only one set of agitators for both leaching and adsorption is required, as ...

Activated 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(6). The loading behaviour of copper cyanide onto activated carbon depends on ...

TREATMENT OF CYANIDE HEAP LEACHES AND TAILINGS

In Carbon-in-Pulp and Carbon-in-Leach cyanidation methods, primary leaching takes place in a series of tanks. Finely ground gold ore is slurried with the leaching solution. The resulting gold-cyanide complex is then adsorbed on activated carbon. CIP conducts the leaching and recovery operations in two separate series of tanks, while CIL conducts them in a single series. Tank operations have ...
