Activated Carbon for Precious Metal Extraction
Precious metal extraction relies on highly efficient adsorption materials and Activated Carbon remains the global standard for recovering Gold, Silver, and other valuable metals from leach solutions. With its exceptional surface area, strong adsorption kinetics, and chemical stability, activated carbon is used across CIP, CIL, CIC, and heap-leach circuits to maximize extraction yields. OozeChem supplies premium grade Activated Carbon for Precious Metal Recovery across the UAE, Gulf, and global markets, tailored specifically for mining, refining, and hydrometallurgical operations.
Why Activated Carbon for Precious Metals?
Activated Carbon is uniquely effective in precious metal extraction due to:
- Extremely high porosity and adsorption capacity
- Selective affinity for metal cyanide complexes
- High mechanical strength for agitation and column systems
- Reusability through thermal regeneration
- Compatibility with gold, silver, and multi metal leach chemistries
These properties make activated carbon a preferred choice for metallurgical plants seeking high recovery rates, low operational cost, and stable performance.
Applications in Precious Metal Extraction
The following sections outline key industrial applications where activated carbon plays a central role.
Gold Extraction Using Activated Carbon
Activated carbon is widely used to adsorb gold cyanide complexes from leach solutions in:
Carbon-in-Pulp (CIP)
Carbon is added after leaching and adsorbs dissolved gold from pulp slurry.
Carbon-in-Leach(CIL)
Leaching and adsorption happen simultaneously, suitable for ores with “preg robbing” tendencies.
Carbon-in-Column (CIC)
Used in heap-leach and pregnant solution circuits for fast flow column adsorption.
Activated carbon ensures high adsorption efficiency and allows repeated regeneration cycles.
Silver Recovery Using Activated Carbon
Silver forms strong complexes in cyanide leach solutions similar to gold. Activated carbon effectively adsorbs:
- Ag(CN)₂⁻ complexes
- Silver from refinery waste streams
- Silver content from dore refining or mixed metal leachates
Industries using activated carbon for silver extraction include:
- Gold silver ore operations
- Base metal refineries
- E-waste silver recovery plants
- Jewelry and precious metal recyclers
Recovery of Other Precious & Valuable Metals
Depending on solution chemistry, activated carbon can also recover:
- Platinum group metals (PGMs)
- Rhodium
- Palladium
- Copper, Nickel impurities (during cleaning stages)
- Residual precious metals in refinery effluents
How Activated Carbon Extracts Precious Metals?
Stage | Description |
Leaching | Ore or concentrate is dissolved using cyanide or suitable lixiviants. |
Metal Complex Formation | Precious metals form metal cyanide or chloride complexes in solution. |
Adsorption on Activated Carbon | Carbon captures dissolved metal ions through porous surface adsorption. |
Carbon Screening / Column Flow | Loaded carbon is separated for elution. |
Elution / Stripping | Metals are desorbed using hot caustic/chemical eluants. |
Electrowinning / Smelting | Metal is recovered as high purity bullion. |
Carbon Regeneration | Spent carbon is thermally reactivated for reuse. |
This cycle repeats multiple times, making activated carbon cost efficient and sustainable.
