ECO-GOLD
ECO-GOLD is our pride. Designed as a carbon solution for mainly gold recovery and other mining industries. Produced by natural STEAM ACTIVATION of virgin COCONUT SHELL CHARCOAL, resulting in unique patterned pores that offer excellent adsorption with reduced leaching and less platelet content, enhancing better recovery of gold and other minerals.
Activated carbon has been used commercially for decades in gold mining. The high specific surface area, good affinity to aurocyanide ions, and abundant resources make activated carbon an efficient material for gold adsorption.
Key Characteristics for Gold Recovery
- Adsorptive Capacity (K-value): How much the activated carbon can absorb
- Adsorption Rate (R-value): Influenced by physical and chemical properties
- Mechanical Strength: Reduces losses from attrition and gold loss
- Particle Size Distribution: Key factor linked to adsorption rate
- Platelets: Controls loss during commercial application
