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 from ...
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 take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.
Gold ore is processed by all-sliming cyanidation CIP (carbon in pulp) at a gold mine in Gansu province of China. The leaching residue (tailing) Au grade is about 0.52 g/t, which is much valuable ...
The carbon in pulp method can also be called all-sliming cyanidation. It is a method in which activated carbon is put into cyanidation pulp to adsorb the dissolved gold onto the activated carbon, and then the gold is extracted from the activated carbon. The carbon in leaching method is developed on the basis of the carbon in pulp method. On the ...

The cyanidation gold extraction process is the main method for extracting gold from ores or concentrates, which is mainly divided into two processes, namely, tank leaching cyanidation method and heap leaching cyanidation method. The heap leaching method is mainly used to .
Whether your final flowsheet uses carbon or resin technologies, the data gathered by SGS will enable you to make important operational decisions and provide capex and opex information for your feasibility study. Carbon Technologies to Recover Gold CIP (Carbon-in-pulp) / CIL (Carbon-in-leach) / CIC (Carbon-in-columns)
5. CARBON IN PULP GOLD ADSORPTION The bulk cyanidation pulp prepared in a bulk leach rate test (HS13918) was divided into discrete sub-samples as listed in Figure 1 for sequential carbon in pulp contact tests. 5.1 Sequential Carbon Contact The adsorption of gold from solution onto activated carbon in a continuous CIP plant
Apr 05, 2019· Cyanidation carbon in pulp gold extraction process - Duration: ... All You Need To Know About Metallurgy ... Gold Leaching Plant in Kenya, October 21, ...
THIOSULPHATE LEACHING – AN ALTERNATIVE TO CYANIDATION IN GOLD PROCESSING ALTERNATIVES TO CYANIDE IN GOLD PROCESSING THIOSULPHATE LEACHING Thiosulphate leaching is a process that ... carbon-in- pulp (CIP) or carbon-in-leach (CIL) processes for the recovery of gold directly from leach pulps. Instead, SGS
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 a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that
Carbon in pulp process. Gold Carbon-in-pulp (CIP) production 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.
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.
2.2 Tank Operations (Carbon-in-Pulp and Carbon-in-Leach) In Carbon-in-Pulp and Carbon-in-Leach cyanidation methods, primary leaching takes place in a series of tanks. Finely ground gold ore is slurried with the leaching solution. The resulting gold-cyanide complex is then adsorbed on activated carbon.
carbon-in-pulp leaching, and electrowinning. Figure 1 shows the layout of the leach section, which consists of one pre-oxidation tank and eight leach tanks with a total residence time of approximately 18 hours. The throughput is 200 t/h with the feed at 75% passing 75 μm and pulp density 50% solids. Oxygen is injected into the tanks to

2. Cyanidation carbon in pulp process. Carbon pulp extraction process (CIP method and CIL method) is to put activated carbon into the cyanidation pulp, and the dissolved gold is adsorbed on the activated carbon, then the gold is extracted from the activated carbon. This process mainly includes the following steps: the preparation of leaching ...
The Production Line of All Sliming Cyanidation CIP Process. All sliming cyanidation CIP method to gold smelting process refers to all the gold ore grinding pulverized pulp (-200 mesh content of 90 ~ 95%), the first cyanide leaching, and then use activated carbon .
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.
The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened ...
is cyanidation for carbon-in-leach (CIL), carbon-in-pulp (CIP) or carbon-in-column (CIC) circuits. The gold leaching process starts with comminution. The run-of-mine ore is crushed and ground to a fine particle size. Water is added to the process to create a mud-like slurry. The slurry is then pumped
Dec 20, 2018· The gold ore cyanide leaching pulp contains a certain amount of Fe2+, Cu2+, Zn2+, S2-, Fe3+ plasma, in addition to the metal sulfide mineral pyrite, pyrrhotite, chalcopyrite and sphalerite. The leaching process consumes a large amount of cyanide and dissolved oxygen, and reduces the cyanide leaching .
Factors influencing the rate of gold cyanide leaching and adsorption on activated carbon, and their impact on the design of CIL and CIP circuits
