Why is coconut shell used in activated carbon?
Coconut shell activated carbon, a product of high-quality coconut shells from Indonesia and Malaysia, has emerged as a valuable resource in the gold extraction industry. Its unique properties, including high wear resistance, fast adsorption speed, and large adsorption capacity, make it an ideal choice for both carbon slurry and heap leaching methods.
Key Features of Coconut Shell Activated Carbon
- Black granular appearance
- High wear resistance
- Fast adsorption speed
- Large adsorption capacity
- Easy desorption
- Regenerable
Gold Extraction Process
Coconut shell activated carbon effectively adsorbs gold ions from cyanide leaching solutions. The adsorbed gold can be recovered through two primary methods:
- Roasting and smelting: Gold-loaded carbon is roasted and smelted at high temperatures to extract pure gold.
- Desorption and electrolysis: The gold cyanide complex is desorbed using a suitable solution, followed by electrolysis to obtain pure gold.
Product Advantages
- Uniform particles: No need for pre-grinding
- Ready-to-use: Requires only washing before application
Handling and Storage
- Avoid mixing: Keep away from hard substances to prevent particle breakage.
- No water immersion: Water immersion can impair the carbon’s performance.
Conclusion
Coconut shell activated carbon offers a reliable and efficient solution for gold extraction. Its exceptional properties and versatility make it a valuable asset in the mining industry.
