Carbon in Pulp

Carbon in pulp, also known as CIP, is a method that is utilized for recovery of gold that has been liberated into a cyanide solution as part of the gold cyanidation method, which consists of a technique for the extraction of gold. This technique was first introduced in 1985 and carbon in pulp is looked on as an uncomplicated and low priced course of action. Given that this is so, it is utilized in nearly all industrial applications where the company of competing silver or copper does not exclude using it. Activated carbon proceeds like a sponge to aurocyanide and other multifaceted ions in solution. Hard carbon particles that are a lot bigger in size than the than the ore particle sizes, and can be combined with the ore and cyanide solution mixture. The gold cyanide complex is adsorbed onto the carbon until it comes to a balance with the gold in the solution. For the reason that the carbon particles are a great deal bigger in size than the ore particles, the coarse carbon can then be divided from the slurry by screening that has a wire mesh.

Loading Gold into Carbon
Leached pulp and carbon are moved in a counter current flow deal involving a succession of tanks, frequently around four or more. In the last tank, fresh or barren carbon is put together with low grade or tailings solution. At this tank the fresh carbon has a lot of activity and can get rid of trace quantities of gold. As it advances up the train, the carbon loads to more and more concentrations of gold, as it comes into contact with higher grade solutions. In most cases, concentrations that are as elevated as 4,000 to 8,000 grams of gold per ton of carbon can be accomplished on the last loaded carbon, as it comes in contact with freshly leached ore and pregnant leach solution also known as PLS. This can be measured by evaluating the quantity of gold that was extracted from the carbon to the quantity of carbon that is utilized.
