Product Overview
Mining operations can't afford to gamble on carbon quality. PSD-GOLD is purpose-built for the rigorous demands of gold recovery circuits, where every gram of gold lost to carbon attrition or poor adsorption kinetics directly impacts the bottom line.
Manufactured from dense, mature coconut shells selected for their high lignin content, PSD-GOLD features a robust granular structure that withstands the abrasive conditions of carbon-in-pulp (CIP), carbon-in-leach (CIL), and carbon-in-column (CIC) processes. The particle shape is optimized for rapid settling and efficient screening, minimizing carbon fines that complicate tailings management.

Key Application Areas
- Gold Recovery — CIP/CIL/CIC Processes: Purpose-built for carbon-in-pulp, carbon-in-leach, and carbon-in-column gold extraction circuits, delivering high gold loading capacity and rapid adsorption kinetics in slurry and solution-phase operations
- Precious Metal Refining: Efficient recovery of silver, platinum group metals, and other precious metals from leach solutions and electroplating effluents through selective adsorption
- Mining Operations: Robust performance in large-scale heap leach and agitated leach mining operations where carbon attrition resistance and mechanical strength are critical for minimizing gold losses
- Carbon Regeneration Circuits: Engineered for repeated thermal reactivation cycles, maintaining >90% capacity recovery after regeneration to reduce operating costs in high-volume gold processing plants
- Tailings & Wastewater Treatment: Recovery of residual precious metals from tailings streams and process wastewater, supporting environmental compliance and resource maximization
- Small-Scale & Artisanal Mining: Available in standard packaging suitable for small to medium gold processing operations requiring consistent carbon quality without complex supply chains
Key Performance Metrics
- High Gold Loading: The micropore structure is tuned for aurocyanide complex adsorption, achieving loadings that compete with the best mining carbons globally
- Low Attrition: 98% minimum hardness means less carbon loss per cycle—translating to lower make-up carbon costs and cleaner tailings
- Rapid Kinetics: The pore size distribution favors fast mass transfer, ensuring gold is captured before it exits the circuit
- Excellent Regenerability: Thermal reactivation restores capacity efficiently, with minimal structural degradation over multiple cycles
