I am very pleased to be here at this seminar on carboninpulp (CIP) technology for the extraction of gold as I am always interested to hear about any new development in any aspect of gold ore processing. We can expect to learn a great deal from the papers to be presented over the next few...
activated carbon (pregrobbing). CIP is a more efficient process for slowerleaching gold ores, and has certain other advantages over CIL, such as smaller carbon elution and regeneration circuits. SGS has developed a carboninpulp (CIP) / carboninleach (CIL) modeling package to .
The process design of gold leaching and carboninpulp circuits 14 JANUARY/FEBRUARY 1999 The Journal of The South African Institute of Mining and Metallurgy Figure 2—The CarbonInPulp (CIP) process Figure 1—ComputerAided Process Engineering (Cape)
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. [1] Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process.
CIL stands for carboninleach. 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 carboninpulp process.
This article serves to discuss the fundamental aspects of gold recovery utilizing the CarboninPulp or CarboninLeach 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
In the gold beneficiation process, activated carbon is a vital tool, used to separate gold that has been dissolved in a cyanide solution, so that it can be recovered. The Gold Cyanidation Process. The gold cyanidation process is a series of steps that vary depending on the characteristics of the deposit and the type of mine.

CIP named Carbon in Pulp. CIP is one kind of gold cyanide gold extraction process. CIP including the completion of gold cyanide leaching and gold cyanide carbon adsorption process. In the early people to engage in gold mining operations it had dis...
Carbon in pulp. Carbon in Pulp (CIP) is a technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process, a gold extraction technique.. Introduced in 1985, 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.
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.
Carboninleach and carboninpulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carboninpulp process adsorption occurs after the leaching cascade section of the plant, and in the carboninleach ...
carboninpulp "renaissance" with the August, 1973, commissioning of the CIP circuit at Homestake Mining Co.''s plant in Lead, South Dakota (then a 2,200 st/d mill). But the fact is, that the process was used commercially at least 22 years earlier, demonstrating once again that much that is new
By replacing the Merrill–Crowe zinc cementation step, carboninpulp (CIP) and carboninleach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores (, highclay ores), at lower capital and operating costs and higher metal recoveries.
Gold Extraction and ... involves contacting the leached pulp with granular carbon in a series of agitating tanks with a sufficient retention time. Selected summary of patented gold recovery processes and examples of commercial mining and recovery gold processes are also provided in this report.
Two main methods Carbon In Pulp (CIP) and Carbon Columns may consist of the most widely used technique for extracting gold today. Both methods use a large tank in the column parallel step where gold is dissolved in the slurry (pulp) through a chemical process .
process, (iii) electrowinning and (iv) ionexchange / solvent extraction. Traditionally, MerrillCrowe process was used to remove gold from a cyanide solution by using zinc dust to precipitate gold from its solution. Carbon adsorption is increasing using in newer plants for gold recovery. Carbon in Pulp (CIP) technique involves contacting the ...
Gold Carboninpulp (CIP) production line is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. High Efficiency When the grade of gold loaded carbon reaches 3000g/t, desorption rate can reach more than 96%.
CIP stands for ''carboninpulp'' where finely ground gold ore mixed with a solution of sodium cyanide in water is agitated in tanks. In the presence of oxygen, the particles of gold form a complex with the cyanide. The pulp is then transferred to l...
CIP ( Carbon In Pulp) process is suitable for the treatment of oxidized gold ore with low sulfur content and mud is unsuitable for the gold ore with highgrade silver as well. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for Carbon In Pulp process in China: PH=1012, sodium cyanide concentration is not less than %, the particle size of ...

Sslurry at a rate of approximately cu. m. per minute (1,000 GPM) is placed in contact with activated carbon. A simplified flowsheet of the CIP Plant is shown in Figure 2. For years it has been known of the affinity of activated carbon to adsorb preferentially the gold and silver in cyanide complex form. This operation takes place in five circular tanks that provide a total pulp ...
Gold processing methods with the Carbon in pulp are often used in largescale gold mining processing, where the active carbon in pulp method used for recovery of gold ore minerals in the washing tank. Tanks that are used are usually equipped with an agitator and air bubbles equipment and tools are designed to maintain solids in suspension in ...
