Carbon in Pulp

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.

Gold CIP process (carbon in pulp) is one of the gold

1.Gold CIP method has strict requirements on activated carbon. If the carbon is not strong enough, it will be broken in the adsorption process, which will cause the loss of gold with the broken carbon. 2.The process is more complicated and contains many process flows. 3.Gold CIP method is not suitable for gold ores with high silver content.

[PDF] Dynamic simulation of the carbon-in-pulp and carbon

Carbon-in-leach and carbon-in-pulp 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 carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously.

carbon in pulp technology for the extraction of gold pdf

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

DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND

In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank.

The process design of gold leaching and carbon-in-pulp

of concentration 10–25 grams of carbon per litre of pulp (0.5 to 1.2% by volume carbon). The carbon is retained in each reactor by means of screens having an aperture of 0.6–0.8 mm which allows pulp to flow through and out of the reactor whilst retaining the carbon in the reactor. The gold aurocyanide complex in the aqueous phase is

Carbon in Pulp Plant

Sslurry at a rate of approximately 3.785 cu. m. per minute (1,000 GPM) is placed in contact with activated carbon. A simplified flow-sheet 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

The gold is then separated from the ore using one of several methods. Floatation involves the separation of gold from its ore by using certain chemicals and air. Cyanidation also involves using chemicals to separate the gold from its contaminants. The carbon-in-pulp method also uses cyanide, but utilizes carbon instead of zinc to precipitate

Comparison of methods for estimating carbon in harvested

Feb 01, 2009· This method assumes that carbon contained in exported wood pulp is released to the atmosphere in the country where pulp is produced and in the same year of production. The same is assumed for other raw materials of semi-finished HWP excluding roundwood, namely chips and particles, wood residues, recovered paper and recovered fibre pulp.

Carbon Adsorption Mine Engineer.Com

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

Ultimate Guide for Gold Cyanidation Process

The pulp and activated carbon are counter-current adsorption, and the activated carbon becomes the gold-bearing carbon after adsorbing the gold in the pulp. When the adsorption is completed, gold-bearing pulp is sent to carbon screen through the air lifter, and the carbon screen separates the activated carbon and pulp. 4. Desorption electrolysis:

Carbon In Pulp Literature Review 1083 Words Internet

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 carbon-in-leach (CIL), leaching and adsorption are done in the same series of tanks.
