Gold recovery solutions
PuroCarbon S.L., a leading supplier of activated carbon, has more than a decade of industrial experience in the field of gold recovery. Our high quality activated carbon solutions are designed to improve the efficiency of gold extraction and purification.PuroCarbon S.L.'s activated carbon offers several advantages in gold recovery:
- High adsorption performanceActivated carbon has a very large specific surface area and a rich pore structure, which allows effective adsorption of gold metal ions and ensures a high gold recovery rate.
- Selective adsorptionactivated carbon has a high affinity for gold ions and can selectively adsorb metallic gold in complex sludges, reducing the adsorption of other impurities.
- Gold purificationActivated carbon not only extracts the gold, but also helps in its purification, eliminating impurities and improving the quality of the final metal.
Gold recycling methods
Coal in pulp (CIP)
Carbon-in-pulp (CIP) is a gold recovery method in which activated carbon is mixed with a slurry (a liquid containing gold-bearing minerals). This process is typically used for the treatment of ores with high gold content.
Advantages:
- Suitable for large-scale mineral processing.
- It can effectively recover gold from low-grade ores.
- Coal regeneration allows it to be used in multiple cycles, thus reducing costs.
Coal in leaching (CIL)
Carbon-in-leach (CIL) is a process in which activated carbon is added to the ore slurry along with a cyanide solution, and the entire leaching process takes place in a single leaching tank.
Advantages:
- Gold can be extracted from ore slurry more efficiently, especially for ores with high leaching effect.
- You can use less activated carbon in the whole process.
- It has better capacity for fine ore particles.
Column carbon (CIC)
The carbon-in-column (CIC) method consists of passing a slurry through a column device filled with activated carbon to prolong the contact time between the gold and the activated carbon, which in turn increases the adsorption efficiency.
Advantages:
- Applicable to low concentration gold ore solution, can obtain high recovery rate.
- Relatively simple operation and easy maintenance of the equipment.
- Suitable for long-term continuous recovery operation.
Activated carbon for gold recovery
Coconut shell granular activated carbon
This activated carbon is manufactured from high quality coconut shells and is mainly used to achieve the extraction of gold and other precious metals from gold-bearing ores due to its superior adsorption properties. With a high specific surface area, developed pore structure and low ash content, it is widely used in gold recovery.
Coconut shell pellet activated carbon
This activated carbon is mainly used to adsorb dissolved gold in gold ore leaching solution. It has very high adsorption capacity and can effectively adsorb dissolved gold ions in cyanide solution through its well-developed microporous and mesoporous structure.
