Activated carbon in touch with a pulp comprising gold may normally recover over 99.5 percent of the gold at the solution in 8 to 24 hours, based on the reactivity of the carbon, the quantity of carbon used along with the mixer's efficacy.
CARBON ADSORPTION RECOVERY. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution. The CIL process is frequently used when native carbon is present in the gold ore. This native carbon will .
Carbon in a Carbon in Pulp / Carbon in Leach circuit is subject to vigorous agitation, leading to abrasion and inevitably, the production of carbon fines. This leads to the loss of gold on the escaping carbon fines to the tailings dam and as carbon is lost, more carbon is required to replenish the total carbon .
Activated carbon is routinely used as part of the gold recovery process at many mines around the world. Activated carbon is used in both carbon in leach (CIL) and carbon in pulp (CIP) techniques. These CIL and CIP techniques recover gold (Au) from pulp or solutions derived from the cyanidation process.
The carbon-in-pulp process Modern gold-recovery techniques depend on the fact that gold (and silver) dissolves in dilute solutions of cyanide. The broken ore from the mine is first ground to a fine powder (typically about 75 µm particle size) in large rotary mills, and the slurry of fine ore and water (the 'pulp') is treated with cyanide in ...

How Gold Works. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon.

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. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.
