The process design of gold leaching and carbon-in-pulp circuits

gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 0001 500. A portion of the loaded carbon is periodically removed from the first adsorption reactor. This loaded carbon may then be subjected to an acid wash by treating the carbon with a hot or cold solution of

ACTIVATED CARBON IN GOLD RECOVERY - Kemix

Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields. The high surface area is contained in the millions of pores of varying sizes, these being

Factors influencing the rate of gold cyanide leaching and ...

Highlights Worldwide gold recovery on activated carbon grew from zero to almost 70% in twenty years from 1980. The stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. Most CIP and CIL plants are overdesigned and operated sub-optimally. Optimum design criteria and operating conditions are easily determined with simple test work ...

Activated carbon also consumes cyanide, so its effect has to be accounted for in the case of carbon-in-leach (CIL) or carbon-in-pulp (CIP) plant flowsheets. Since cyanide is an expensive reagent, often a major component of plant operating costs, it is important that the scale-up of cyanide consumption from laboratory to plant be representative.

Carbon Stripping Denver Mineral Engineers

Loaded carbon is first presoaked with sodium cyanide/sodium hydroxide solution. The presoak solution is drained from the carbon bed and an alcohol solution is added to the vessel. The unit is then switched to the batch distillation mode. Within a few hours, the alcohol is concentrated in the overhead condenser tank. The tower bottoms solution ...

DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND CARBON-IN-LEACH ...

activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon-in-pulp (CIP) and the carbon-in-leach (CIL) processes, have been widely used since the 1970s. Due to the economic

ACTIVATED CARBON IN GOLD RECOVERY - Kemix

Carbon-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

Oxygen Sparging Improves Gold Leaching - Eriez Flotation

The dissolution of gold through cyanidation, either Carbon in Pulp (CIP) or Carbon in Leach (CIL), is an oxidizing reaction. Generally added oxygen, in the form of dissolved oxygen in solution, improves the process as the rate of gold dissolution is directly proportional to the amount of dissolved oxygen in solution.

Kemix - Carbon Adsorption

There are predominantly three methods employed in industry to adsorb leach gold from a pulp stream onto activated carbon. The methods are Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Pumpcell technology. CIL and CIP are typically counter current operations while the Pumpcell technology makes use of the carousel mode of operation.
