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.

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching …

Stange* Introduction Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon-in-pulp circuit (CIP). ...

Today's gold mining operations optimize efficiency and output through the use of superior Haycarb gold recovery carbon technology. Our high density carbons with particle to particle consistency in activity and shape is an ideal solution for applications in CIL (carbon-in-leach), CIP (Carbon-in-pulp) and CIC (carbon-in-column) processes.

The Simulation of Gold Leach, Carbon-in-Leach and Carbon-in-Pulp Absorption Circuits 1. INTRODUCTION The control and optimization of carbon-in-pulp and carbon-in-leach plants has been the subject of much research and development. As a result of many years' experience in

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

This article serves to discuss the fundamental aspects of gold recovery utilizing the 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

Carbon-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 agitated tanks containing activated carbon.

circuits is a preferred method for gold recovery from low grade surface deposits and waste rock because of its low capital and operating costs. CARBON-IN-PULP In CIP operations, mined ore is milled and mixed with water and thickeners, creating a slurry of ore and water called pulp. The pulp is then pumped to air-agitated leaching vessels, where ...

The nature and chemistry of an ore deposit determine the processing method used in gold production. There are many processing techniques for gold ore; the most common is cyanidation in carbon-in-leach (CIL), carbon-in-pulp (CIP) or carbon-in-column (CIC) circuits. Gold leaching plants use valves for numerous flow control and isolation services.

Gold Leaching( carbon in leach) was developed from CIP( Carbon In Pulp), is characterized by less process flow, timesaver in the leaching process, thus reducing the production expenditure. Besides, advanced extraction technology improving the efficiency of gold extraction. The CIL production line is wider use than CIP in the mineral industry.
