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). The reagent and utilities operating costs associated with leaching, adsorption, elution and ...
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.
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 …

The metallurgical performance of carbon-based plants depends primarily on the rate of mass transfer of gold cyanide from the leach solution onto the carbon granules in the adsorption tanks, which in turn is a sensitive function of parameters such as the rheology of the pulp, the intensity of agitation of the pulp and the concentration of gold ...
Leaching and adsorption: pump slurry ore into the double-impellers leaching tanks, there are always 6-8 tanks working togheter; add cyanide solution into first one or two leaching tanks, add activated carbon into the rest gold leaching tanks; activated carbon adsorb gold and become the loaded gold carbon, the loaded gold carbon lift into the ...
Cyanidation, or the metallurgical process of extracting gold from ore with cyanide leaching agents, has long been a primary method of gold beneficiation.Widely used throughout the world, one incredible material helps to make gold recovery from a cyanide solution possible; with its ultra-porous structure, activated carbon is a powerful adsorbent used throughout a number of industries to ...

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 ...
Introduction Gold CIL Plant is one common process in gold ore dressing. Its famous feature is the simultaneous gold leaching and adsorption. This CIL method has high recovery rate and high degree of automation. Gold Carbon In Leaching leach
Outotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations.
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 Ity Gold Mine in Côte d'Ivoire has been in operation for more than 20-years, previously as a heap leach operation. Recent construction of a carbon-in-leach plant has allowed for an increase in …
basic parts of carbon in leach plant. gold plant will be that of the leaching and carbon-in-pulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and regeneration would typically make up some 15% of total operating cost, whilst the capital costs associated with these areas is about 16% of the total.
In CIP, the carbon is mixed with the cyanide leach solution, and agitated in the leach tanks, and agitated with the ore while the gold is being dissolved. This assures a rapid interface between the carbon and the gold loaded cyanide solution. Granular, hard carbon is used, in the size range of 10-16 mesh. The carbon is then removed by screening ...

Gold cyanide carbon in leach plant introduction: CIL process is widely used in the newly built leaching plants recent years, and a lot of plants are changing into CIL as well.CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.
The ﬂotation tailings containing the unrecovered gold from the primary circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL).
Carbonaceous matter in a gold ore has been shown to act like activated carbon and adsorb solubilized gold from cyanide solution during leaching. It is thought that the dispersion of the carbonaceous matter and its fineness (less than 20 μm) account for the high adsorption and loss of gold during cyanidation ( Sibrell and Miller, 1991 ; Pyke et ...
Oct 20, 2014· The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t).
