Granular Activated Carbon (GAC) for Gold Extraction

Our apricot shell-based GAC is engineered for heap leaching gold extraction. With 30 years of manufacturing experience, it’s a cost-effective alternative to expensive coconut shell carbon—delivering comparable gold recovery at lower costs.

Core Advantages​

• Strong Adsorption: Iodine value 500-1100 mg/g, specific surface area 500-1400 m²/g—efficiently captures gold cyanide complexes for maximum recovery.​

• Low Impurities: Ash ≤5%, heavy metals <1 ppm—minimizes contamination and refining costs; stable in alkaline cyanide leaching (pH 10-11).​

• Cost-Saving: 30% cheaper than coconut shell carbon, cutting processing costs by 22%. Wear resistance ≥92% meets heap leaching needs.​

• Custom Sizes: Standard5-10 or 6-12 mesh , plus 5-8/4-8 mesh options—ensures optimal permeability and uniform adsorption.​

Application: Heap Leaching​

Ideal for low-grade gold ore heap leaching. Acts as a key gold capture medium with >99% adsorption rate and 1000-5000x enrichment factor (on par with coconut shell carbon). Compatible with desorption-electrolysis; ≥95% regeneration rate.​
