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

carbon-in-pulp circuits by W. 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).

Carbon-in-Pulp - ScienceDirect

2016.1.1 The average carbon activity in a circuit is mainly a function of the efficiency of the carbon regeneration process (i.e., not the activity of the new carbon). The importance of returning the barren carbon to good kinetic activity has long been known ( Avraamides and La Brooy, 1987 ).

CIP History – Denver Mineral Engineers

in a carbon-in-pulp cyanidation circuit that was remarkably similar to those in operation today. The CIP cyanidation circuit consisted of three 40-ft-dia leach tanks followed by three 40-ft-dia CIP adsorption vessels. All were equipped with low-speed agitators and arranged in stepped, one-ft height sequences to provide for gravitational flow of ...

Carbon-in-pulp - ScienceDirect

2005.1.1 Carrier-in-Pulp (CIP) method, which is similar in principle with the Carbon-in-Pulp technology for gold recovery from ores, was proposed to recover these heavy metals from molten fly ash. Unlike the traditional Carbon-in-Pulp process, the carrier or adsorbent in the Carrier-in-Pulp method is not only limited to carbon; other materials

A QUANTITATIVE STUDY INTO CARBON-IN-PULP ADSORPTION OPERATIONS

Carbon-in-pulp(CIP) and carbon-in-Ieach(CIL) remain the most effective, and widely used processes for gold recovery from cyanided pulps. The extensive use of carbon in such processes have prompted many researchers to investigate the mechanism of metal cyanide adsorption. Not only has this provided many viable theories in the understanding of the

Gold CIP and CIL process optimization in a capital constraint

Introduction. The well-known carbon-in-pulp (CIP) and carbon-in-leach (CIL) gold recovery processes are fairly robust. Considering the constantly changing characteristics of run-of-mine (ROM) ore, a robust process is in general a great advantage for a mineral processing plant. The disadvantage, however, is that because less input is required ...

How to Differentiate Gold CIP CIL Production Line?

2017.1.4 Gold absorbs on to the activated carbon, which flows counter-current to the pulp, while screens separate the barren pulp from the gold-loaded carbon. Carbon-in-leach (CIL) is a simultaneous leach ...

The application of activated carbon for the adsorption

Introduction. The carbon-in-pulp or carbon-in-leach (CIP and CIL) processes have been the main commercial processes on almost every gold plant built since 1980 (Fleming, 1992; Van Deventer, 1984) with a stable

Factors influencing the rate of gold cyanide leaching and

2011.5.1 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 rapidly to all the gold producing regions of the world. The percentage of annual global gold production by activated carbon-based processes grew
