Carbon in pulp - Wikipedia

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.

The leaching and adsorption behaviour of gold ores

The effect of preg-robbing on the enhanced extraction of gold in the presence of activated carbon was closely examined for a number of different ore types. For the Telfer oxide ore, which was not found to be preg-robbing, enhanced gold extraction was observed at low cyanide concentrations, but not at high concentrations, as the gold was completely extracted by

gold extraction by carbon in pulp process

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 . READ MORE
