Carbon in Pulp Plant

Carbon is advanced such as to satisfy daily production requirements. An adequate amount of fresh or reactivated carbon is added daily to the last tank in the circuit. Carbon concentration in the pulp averages 24 grams of carbon per liter of pulp. Carbon loading, expressed in grams per metric ton of carbon is shown on Table 2.


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

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

Carbon In Pulp Literature Review 1083 Words |

Interstage screens between the tanks prevent the carbon from moving downstream. The gold value of the pulp decreases downstream, and the gold loading on the carbon increases upstream, with the highest value in the first tank. In a variation to this method, termed carboninleach (CIL), leaching and adsorption are done in the same series of tanks.

Carbon in pulp Wikipedia

Leached pulp and carbon are transferred in a counter current flow arrangement between a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with low grade or tailings solution. At this tank the fresh carbon has a high activity and can remove trace amounts of gold (to levels below mg/L Au in solution).

The tanks are normally mechanically agitated and each will contain a batch of carbon of concentration 10–25 grams of carbon per litre of pulp ( to % by volume carbon). The carbon is retained in each

Carbon Adsorption Mine

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton. If the ore is a high grade, it may be feasible to ...

Difference Between Carbon In Pulp And Carbon In Leach

2019515 · The selfcontained device collects slurry samples from Carbon In Pulp and Carbon In Leach tanks to determine the distribution of the activated carbon in the pulp for each tank, to an accuracy of ± grams of carbon per litre of pulp. At Gekko we strongly believe that the new Carbon Scout technology can make the difference between ...


THE CARBONINPULP TANK. Gerace Gerald. January 1st, 2019. In the CIP process, activated carbon is used to adsorb the gold directly from the cyanided pulp in a series of large adsorption tanks. Pulp flows continually from the first vessel to the last in the series, and the carbon is transferred intermittently by pumping in the opposite direction.

Carbon in pulp Wikipedia

Carbon in pulp process. 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.

Carbon in Pulp | Gold CIP JXSC Machine

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 ...

CIP/CIL Modelling AusIMM

Gold on carbon/gold in solution ratios of >1000:1 are achievable in many cases. The distribution of that carbon between the stages (within reason) is irrelevant. The concentration of carbon in the pulp varies with the size of the tanks, so it is irrelevant. Gold extraction efficiency is determined by:

Estimation of gold inventory in large carbon in leach tanks

The carbon transfer is carried out by pumps with intake submerged – m below the surface. The mixing in the tank may push some carbon from the bottom of the tank to the surface producing possible variation of the gold grade during the transfer as indicated by Morrison (2008, Figures. 11–9). Samples were then taken at the beginning ...
