Modelling of the Process Chemistry With regard to the modelling of the process chemistry, adequate models for concurrent leaching and adsorption
This document discusses optimizing gold CIP and CIL processes in a capital constrained environment through the use of modeling and economic analysis. It presents two case studies from South African gold plants. The well-known Nicol-Fleming kinetic adsorption model is used, along with economic modeling, to determine the operational conditions that will maximize …
From the late 1970s onward a variation of CIP, carbon-in-leach (CIL) which combined the leach and adsorption stages, became the preferred circuit design in most parts of the word." "The carbon-in-pulp (CIP) process has been the dominant gold recovery process since the early 1980s. CIP has proven to be very adaptable for a wide range of ores and ...
SYNOPSIS To date developments in the simulation of carbon-in-pulp (CIP) adsorption circuits have focused primarily on the modelling of adsorption. This series of three papers describes a development in a direction that has received less attention, i.e. the need for a detailed description of the movement of carbon and slurry in continuous CIP and carbon-in-Ieach (CIL) plants. A …
The aim of modelling and simulation of CIP/CIL tanks is limited to either refining the models used for simulations or optimizing the process using operating parameters. For improving the models to simulate CILs, van Deventer and Ross (1991) reviewed the developments in CIP systems and concluded that preg-robbing is an important phenomenon in ...
CIP vs CIL. 1. CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry …
The CIL process requires the desorption of gold in the leaching tank, while the gold desorption in the CIP process is performed after solid-liquid separation. Overall, both CIP …
A continuous CIP/CIL model can be used to predict outcomes from the CIP/CIL processing of different ores, or for evaluating the effects of non-idealities in CIP/CIL circuits, such as preg-robbing.

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 and adsorption …
ENGLISH ABSTRACT: This article focuses on the use of a model in combination with economic analysis to extract maximum value out of current gold operations, without the need for additional capital. Two South African case studies (CIP and CIL) are presented to show that an optimum point of operation exists. This optimum point of operation, however, depends on several …
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 …

CIP AND CIL CIRCUIT MODELLING The SGS carbon-in-pulp (CIP) / carbon-in-leach (CIL) modelling package is used to estimate the performance of a full-scale CIP or CIL plant and to derive the optimum design criteria based on the results of small scale experiments. It is a powerful design tool that uses the results
The CIL process requires the desorption of gold in the leaching tank, while the gold desorption in the CIP process is performed after solid-liquid separation. Overall, both CIP and CIL processes utilize activated carbon for gold adsorption, but there are some differences in the gold recovery steps and processes.
A typical CIP or CIL circuit is shown in Figure 1. The process is regulated by the elution schedule. Carbon addition and carbon transfer are based on when the required mass of carbon needs to be ...
In this paper a CIP/CIL model was developed which accounted for the leaching of gold from the ore, preg-robbing of gold onto the ore surface and adsorption of leached gold onto activated carbon. A ...

Carbon In Leach (CIL) and Carbon In Pulp (CIP) are two commonly used methods in the gold extraction process. Although both methods involve the use of activated carbon to adsorb gold, …
the leaching and CIP/CIL processes. These data allow the simulator to be calibrated for the particular scenario that is to be examined and could be obtained from the laboratory, pilot plant and/or full-scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming
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 affect the adsorption of gold are discussed. Finally, performance monitoring methods that help control the operation of the CIP/CIL process are discussed. 2.

There are three main carbon adsorption processes used in gold mining: carbon-in-pulp (CIP), carbon-in-leach (CIL), and carbon-in-columns (CIC). CIP and CIL processes recover gold directly from ore pulps or slurries containing up to 55% solids using activated carbon, while CIC treats solutions from heap leaching. CIP and CIL generally have lower capital costs than the …
CIP and CIL method is a new process for processing precious metal-containing pulp on the basis of the conventional cyanide gold extraction method. In CIP process, leaching and adsorption are two operations, the leaching tank is used for cyanide leaching of the slurry, and the carbon slurry tank is used for adsorption of gold by activated carbon.
Case studies for both a CIP plant and a CIL plant are presented. The CIP case study. A plant evaluation on a 180 000 t/month CIP plant was performed. The plant consists of six Kemix pump cells in a carousel flow arrangement, a hydrochloric acid pre-wash, high-pressure elution at 125°C, kiln regeneration, and electrowinning.
