PSD-GOLD Coconut Shell Carbon – 98% Hardness for CIP/CIL Gold Mining

Key Features

• ≥1050 mg/g Iodine Value & High Gold Loading

  Highly developed micropore network delivers exceptional adsorption capacity for gold cyanide complexes, maximizing gold capture per ton of carbon and reducing inventory requirements in high-throughput CIP/CIL circuits.

• ≥98% Ultra-High Abrasion Hardness

  Industry-leading mechanical strength minimizes particle attrition and fine generation in violent agitated slurry environments, drastically reducing gold loss to tailings and supporting dozens of regeneration cycles with stable particle integrity.

• Optimized Micro-Mesopore Structure

  Precisely balanced pore distribution efficiently adsorbs aurocyanide ion pairs while enabling straightforward, high-recovery elution stripping, ensuring rapid kinetics and deep loading capacity per cycle.

• Excellent Thermal Regenerability

  Stable coconut shell structure retains the vast majority of original adsorption capacity after proper thermal reactivation, enabling repeated reuse and significantly lowering total carbon consumption cost over the mine life.

• Tight Mining-Grade Size Distribution

  Standard 6×12 mesh grading with uniform particle sizing ensures compatible screen separation efficiency across all conventional CIP/CIL/CIC systems and elution columns, preventing carbon lock-up and fines bypass.

Applications

• CIP/CIL Gold Recovery Circuit Durability: CIP and CIL circuits involve intense agitation and inter-particle abrasion that destroys softer carbon, causing gold-bearing fines to escape through screens. PSD-GOLD's 98% hardness minimizes attrition loss, directly reducing gold loss in tailings and lowering annual carbon replacement demand.

• Heap Leach Solution Clarification: Clarified pregnant liquor from heap leaching requires rapid gold cyanide complex adsorption. PSD-GOLD's optimized micro-mesopore structure achieves high loading capacity and fast kinetics, maximizing recovery from lower-grade solutions.

• Carbon-in-Column (CIC) Recovery: Packed column adsorption for low-grade pregnant liquor needs consistent particle sizing and high mechanical integrity. PSD-GOLD's tight 6×12 mesh distribution and extreme hardness maintain screen efficiency and prevent carbon lock-up.

• Precious Metal Solution Refining: Gold, silver and platinum group metals from electroplating waste and industrial process solutions require selective adsorption. PSD-GOLD's pore structure effectively captures precious metal cyanide complexes.

Technical Advantages

• Approximately 30–40% lower attrition loss compared to standard water-grade coconut carbon, directly reducing gold loss in tailings.

• High gold loading capacity reduces required carbon inventory and elution frequency, improving overall plant throughput.

• Consistent batch-to-batch quality ensures stable adsorption performance, making recovery rates predictable across production campaigns.

• Manufactured and tested in accordance with international mining industry quality standards with full batch traceability.

FAQ

Q: What is the difference between PSD-GOLD and PSD-A0?

A: PSD-A0 is formulated for water treatment with balanced organic removal. PSD-GOLD is engineered specifically for gold recovery with optimized pore structure, ultra-high hardness and enhanced wear resistance for abrasive slurry environments.

Q: How many regeneration cycles?

A: Under proper elution and controlled thermal regeneration, typically 20–30 full cycles. Actual life depends on slurry composition and regeneration quality.

Q: Does PSD-GOLD work for silver recovery?

A: Yes. The same pore structure captures silver and other precious metal cyanide complexes, suitable for mixed gold-silver ore processing.
