This invention relates to the recovery of gold from carbon fines. Carbon fines are produced when carbon, which is used in a carbon-in-leach (CIL) or carbon-in-pulp (CIP) process for the recovery of gold, is broken. Typically, these fines, loaded to some extent with gold, exit from a last adsorption stage of the process and are then lost.

The following calculated results were obtained from the computer simulation of the elution column using Ok Tedi plant design data. The advantages and disadvantages of each procedure are discussed.
carbon in pulp process in the gold industry in the 1980s, many innovative techniques for preparing leached slurries and separating carbon from pulp have become firmly established. These techniques have proven to be equally applicable to resin separation from pulps in RIP contactors. Uranium recovery
The process design of gold leaching and carbon in pulp . SAIMM. African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically. 80% passing 75µm) to ensure that all non refractory gold is readily accessible for cyanide leaching.
Carbon in pulp. 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
The recovery of gold cyanide from a cyanide leach pulp ( Process) by contact thereof with activated carbon has become an extremely successful method of recovery of dissolved gold resulting in high recoveries and, correspondingly, low losses in the tailings.

Jan 01, 2022 · "The carbon-in-pulp (CIP) process has been the dominant gold recovery process since the early 1980s. CIP has proven to be very adaptable for a wide range of ores and circuit configurations. including key requirements for good carbon management, the results of benchmarking and industry surveys of carbon circuit over 20 years, the value of
Leaching dissolves the gold out of the ore using a chemical solvent. 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.
The GK provides complete, simple and robust processing solutions with high recovery of both coarse and fine precious metals, especially fine gold recovery, from dump tailings, rubble beds & alluvial sands.
