Carbon in Pulp

Gold Carbon-in-pulp (CIP), Gold CIP Production Line

Gold Carbon-in-pulp (CIP) production line is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. 

High Efficiency

When the grade of gold loaded carbon reaches 3000g/t, desorption rate can reach more than 96%.

Low energy consumption

Due to the same temperature and fast working, the energy consumption is 1/2-1/4 of regular system.


The time of desorption electrolysis is 12 hours shortened by 50-70%. With three security measures, system intelligent.

No cyanide&Automatic control

Without adding NaCN in desorption solution, installed level liquid control system, temperature control system.

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.

CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high grade silver as well. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for CIP process in China: PH=10-12, sodium cyanide concentration is not less than 0.015%, the particle size of activated carbon is 1.0-3.35mm, the best choice of carbon is coconut shell activated carbon, and the slurry concentration is 40-45%.

  2. Grinding and Classification
  3. Thickening
  4. Leaching
  5. Adsorption
  6. Desorption of Gold-loaded Carbon and Electro-deposition

There are several desorption methods. In China, the general application methods are Zadra desorption method, high temperature, and high-pressure desorption method (hereinafter referred to as HTHP method) and integral pressure desorption method (hereinafter referred to as IP method).
