Coconut shell activated carbon is a high-performance material known for its exceptional adsorption capacity, high hardness, and low ash content. At Zhongci Environmental Ceramics Materials (www.chempackings.com), we specialize in manufacturing and supplying top-grade coconut shell activated carbon for a wide range of industrial applications, including gold recovery, water purification, air filtration, and more.
1. Industries That Rely on Coconut Shell Activated Carbon
Our coconut shell activated carbon is trusted in the following sectors:
- Gold Mining (CIP/CIL processes): Extracts gold from cyanide leach solutions with high efficiency.
- Water Treatment: Purifies drinking water and treats wastewater by removing chlorine, organic compounds, and odors.
- Air & Gas Purification: Eliminates volatile organic compounds (VOCs), harmful gases, and industrial emissions.
- Food & Beverage Industry: Decolorizes and purifies liquids such as sugar syrups, juices, and alcohol.
- Pharmaceutical Production: Used in the purification of active pharmaceutical ingredients and solvents.
- Energy & Electronics: Supports the development of supercapacitors and energy storage devices due to its micro-porous structure.

2. Understanding Iodine Values in Activated Carbon
Iodine value is a key indicator of activated carbon quality, reflecting its micropore content and adsorption ability. Here’s how it breaks down:
| Iodine Value | Performance | Applications |
| 600–800 mg/g | Moderate adsorption | Basic filtration |
| 800–1000 mg/g | High adsorption | Water and air purification |
| 1000–1200 mg/g | Superior adsorption | Gold recovery, gas-phase purification |
The higher the iodine value, the more effective the carbon is at adsorbing small molecules and gold cyanide complexes — making it crucial for industries like gold mining.
3. Why Choose Coconut Shell Activated Carbon Over Other Types?
Compared to coal-based and wood-based activated carbon, coconut shell activated carbon stands out in several ways:
| Feature | Coconut Shell AC | Ordinary AC |
| Raw Material | Coconut shells | Coal, wood, peat |
| Pore Structure | Rich in micropores | Varies (coal = mixed; wood = macropores) |
| Hardness | Very high | Medium to low |
| Ash Content | Low | Higher (especially in coal AC) |
| Surface Area | 1000–1200 m²/g | 500–1000 m²/g |
| Ideal Use | Gold mining, water purification | General filtration, air treatment |
At Zhongci Environmental Ceramics Materials, we offer coconut shell activated carbon that delivers superior performance, especially in applications where durability and microporous adsorption are critical.
4. Our Recommendation for Gold Mining Applications
In the gold extraction industry, particularly in CIP (Carbon-in-Pulp) and CIL (Carbon-in-Leach) processes, only premium-quality activated carbon should be used. Zhongci’s coconut shell activated carbon is specially developed for these rigorous requirements, featuring:
- Iodine Value: 1100+ mg/g
- Mesh Size: 6×12 or 8×16 (for optimal flow and adsorption kinetics)
- Hardness: ≥ 98% (to withstand attrition in processing tanks)
- Ash Content: ≤ 3% (to prevent contamination)
- High Microporosity: Maximizes gold cyanide adsorption
Our products ensure high adsorption efficiency, excellent mechanical strength, and long service life — translating to improved gold recovery and reduced carbon losses for your operations.
