In the gold industry, the use of activated carbon to separate gold from cyanide leaching solutions has become an industry standard for efficient gold recovery in Carbon-in-Leach (CIL), Carbon-in-Pulp (CIL) and Carbon-in-Column (CIC) operations.
The gold cyanidation process is a primary method of gold beneficiation Activated carbon is a critical component in the beneficiation of gold ore. Allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex.
Depending on the deposit some silver ores may also be processed via cyanidation Here too, activated carbon is the catalyst for recovery of this precious metal.
In choosing an activated carbon for use in gold recovery, the characteristics below are of key importance. These characteristics vary as a result of both the physical and chemical properties of the material, which differ depending upon the source material and processing method used to produce the activated carbon.
- Adsorptive Capacity (Know as K-value)
- Adsorption Rate (Known as R-value)
- Mechanical Strength and Wear Resistance/Hardness
- Particle Size Distribution
