The carbon in pulp method can also be called allsliming 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.
By using the most durable coconut feedstock, to withstand the rigorous carbonization and activation process, we can consistently manufacturing quality activated carbon for gold extraction. We manufacture products that are used extensively in Carbon in Column (CIC), Carbon in Pulp (CIP) and Carbon in Leach (CIL) applications.
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%.
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.
Calgon Carbon''s highquality GACs are proven to maximize recovery efficiencies by reducing gold loss and minimizing carbon consumption when used for CarboninLeach (CIL), CarboninPulp (CIP) and CarboninColumn (CIC) gold extraction techniques.
The benefit of the Carbon Scout is the provisioning of a single sampling point at ground level, in addition to automated carbon density measurement. Expert interpretation of data will result in realtime circuit optimisation in carboninleach and carboninpulp circuits, reducing soluble gold .
Activated carbon is widely used for gold recovery from cyanide leach liquors via carboninleach (CIL) or carboninpulp (CIP) technology. From all the base metals cyanide complexes typically present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded
Gold absorbs onto the activated carbon which flows into the pulp, while screens separate the barren pulp from the goldloaded carbon. Carbon in Leach (CIL) It is the simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pregrobbing ...
CarbonInPulp With carboninpulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening.
CarbonInPulp With carboninpulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. Carbon is then added which adsorbs the gold. This method has a high gold recovery percentage.
Oct 26, 2012· The feasibility of a process involving the use of activated carbon in a multistage column (NIMCIX contactor) for the recovery of gold from unclarified pregnant solutions was investigated on pilotplant scale. It was found that satisfactory extractions, corresponding to a recovery of percent, can be achieved with an average gold concentration of in the barren solutions from a ...
CarbonInLeach. Carboninleach combines leaching with the carboninpulp process, creating a single unit process operation. Usually this method is chosen when native carbon (a high organics load) is present in the gold ore, adsorbing the leached gold and preventing its recovery.

Cyanidation carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution . In 1970s, with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold, make recycle the carbon and reduce the cost, and easy to process the gold ...
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. Hard carbon particles (much larger than the ore particle sizes) can be mixed with the ore and cyanide solution mixture.
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%.
Carboninpulp The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or "pregnant" with gold. Carboninleach This process is very similar to the CIP process.
Processing of ore at Macassa starts with crushing and grinding to a particle size of 45μm before it enters the leach tanks for cyanidation. Then, it flows through a carboninpulp (CIP) circuit recovery system. The concentrate is melted in an inductotherm induction furnace where doré is poured and typically contains 85% to 88% gold.
Apr 11, 2018· Gold Carboninpulp (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. Chat Online on .
Activated carbon in contact with a pulp containing gold can typically recover more than % of the gold in the solution in 8 to 24 hours, depending on the reactivity of the carbon, the amount of carbon used and the mixer''s efficiency. The loaded carbon is then separated from the pulp by screens that are air or hydro dynamically swept, thus ...
CarboninPulp (CIP) and CarboninLeach (CIL) processes have surface areas of about 1000 m²/g 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 high surface area is contained in the millions of pores of varying sizes, these being
Gold Carboninpulp (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. CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.
The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen trating factor of about 1 000–1 500.
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 ...
