Carbon in Pulp (CIP) Vs Carbon in Leach (CIL) Vs Carbon in Column (CIC)Carbon in Pulp (CIP) It is the sequential leach then absorption of gold from ore. During CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution, In the absorption stage, this solution flows through ...
These carbon recovery techniques include: Carbon-in-pulp 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. Carbon-in-leach
expenditure for a carbon-in-solution plant would be about 33 per cent higher than that of a resin-in-solution plant. The operating expenditure for a resin-in-solution plant is expected to be only 60 per cent of that for a carbon-in-solution plant. Keywords: resin-in-solution, carbon-in-solution, heap leach. * Mintek, Private Bag X3015, Randburg ...
In the gold industry, the use of activated carbon to separate gold from cyanide leaching solutions has become an industry standard for efficient gold recovery in Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Carbon-in-Column (CIC) operations.
pulp in an environment appropriate for leaching in the CIP reactors. This additional leaching provides additional economic benefit. The CIL process The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach .
Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon This has spawned technologies such as CIP (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns) More recently, SGS has lead the gold processing industry with the development of resin-based technologi.
Several economic comparisons have been made between carbon systems and Merrill-Crowe systems. One of these, a systematic comparison completed by DeMent and King (1982) is summarized below. Five separate conventional mills involving both Merrill-Crowe and the CIP processes were compared from an economic viewpoint. The gold concentration on the feed leach liquor ranged from 0.428 to 0.054 oz of ...
A major use of activated carbon in mining is in gold recovery, where granular activated carbon (GAC) is used for adsorption of the gold-cyanide complex in carbon-in-pulp (CIP) and carbon-in-leach (CIL) systems, or in carbon-in-column (CIC) systems after a heap leach operation carbon.
uses of carbon in gold extraction - csdpmap . Activated carbon in contact with a pulp containing gold and/or silver can typically recover more than % of the metals 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.
Two primary methods, Carbon In Pulp (CIP) and Carbon Columns probably comprise the most widely utilized techniques for extracting gold, now days. 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.
The carbon-in-leach system is similar to the carbon-in-pulp system. The primary difference between the carbon-in-pulp system and carbon-in-leach system is that in the former, there are mixing tanks for cyanidation leaching prior to the carbon adsorption stage. In a carbon-in-leach system, cyanidation is conducted in the presence of carbon.
carbon and gold in carbon in pulp (CIP) and carbon in leach (CIL) applications. However, this reactor design also has some drawbacks. The strong correlation between solids particle size and the required mixing power for solids suspension makes it difficult to achieve a .
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 0.01 mg/L Au in solution).

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 materials, agitation leaching and countercurrent carbon adsorption, gold-loaded carbon ...
Carbon in pulp vs carbon in leach - binq miningalgon carbon type grc granular carbons are coconut-based activated for gold recovery operations- in carbon in leach cil, carbon in pulp cip, and heap for carbon that, in the past, was lost in the pre-attrition step and or process.
Dec 05, 2012· In Carbon in Leach (CIL), Carbon in Pulp (CIP), and Heap Leach circuits, it is essential that the carbon used provides excellent process performance, minimal losses due . Carbon-in-pulp-in-leach, Carrying Charge | Mining & Metallurgy. Gold Prospecting & Gold Mining of Placer Deposits. Gold Exploration and extraction.
Nov 28, 2012· The main difference between the CIL and CIP processes is that in the. what is the difference between carbon in leach process and carbon . what is the difference between carbon in leach process and carbon in pulp process (14 Jun 2012) Caiman supply Mining and construction equipment for mineral handling.
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.
Jan 04, 2017· In the CIL (Carbon in Leach) or CIP (Carbon in Pulp) plants while the precious metals are being dissolved by the cyanide solution in the large .
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 ...
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 .
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.
