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

Activated carbon is used to recover gold in solution from various gold circuit designs including carbon-in-pulp (CIP), carbon-in-column (CIC), and carbon-in-leach (CIL) processes; however, the characteristics and durability of the activated carbon can vary. Handling this medium poses chal-lenges when fine carbon losses occur in the CIP, CIC ...

A dynamic CIP/CIL process simulation using MATLAB SIMULINK

Carbon in Pulp (CIP) Vs Carbon in Leach (CIL) Vs Carbon in Column (CIC)Carbon in Pulp (CIP) It is the sequential leach then absorption of gold from ore. During 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 ...

3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.

What is the difference between CIP and CIL gold leaching ...

The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and Australia, from where they spread ...

DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND …

Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns). More recently, SGS has lead the gold processing industry with the development of resin-based technologies.

carbon in leach process for gold recovery

Abstract. A semi-empirical model was developed to represent a carbon in leach/carbon in pulp (CIL/CIP) circuit for recovery of gold and silver. The model uses …

ACTIVATED CARBON IN GOLD RECOVERY - Kemix

The tailings dumps were hydraulically mined, reprocessed and stored in an engineered impoundment located 10km south east of Kalgoorlie. From the 60 million tonnes of tailings mined 695,000 ounces of gold was recovered by Carbon-in-Circuit (CIC) and Carbon-in-Pulp (CIP) leach and absorption circuits (Kaltails 1998; Normandy 1998).
