Customer Case Study: Improving Gold Recovery Efficiency with High-Strength Coconut Shell Activated Carbon in Egypt

Background

An Egyptian gold processing plant specializing in gold extraction through the Carbon-in-Pulp (CIP) cyanide leaching process was facing challenges with unstable gold recovery performance.

The activated carbon previously used in the plant had poor mechanical strength, causing excessive carbon breakage during operation. A large amount of fine carbon powder was lost with tailings, resulting in gold loss and increased carbon consumption. In addition, inconsistent iodine values between batches led to unstable adsorption capacity, affecting overall production efficiency.

The customer needed a more durable and stable activated carbon solution to improve gold adsorption performance, reduce carbon loss, and maintain consistent gold recovery.

Customer Challenges

During daily CIP operation, the customer experienced several key issues:

1. High Carbon Breakage and Gold Loss

The previous activated carbon had insufficient abrasion resistance. Under continuous agitation inside the adsorption tanks, carbon particles were easily crushed into fine carbon powder.

The lost fine carbon carried adsorbed gold into the tailings stream, increasing gold losses and reducing recovery efficiency.

2. Unstable Adsorption Performance

The iodine value of the previous carbon varied significantly between production batches, resulting in inconsistent adsorption capacity and unstable gold recovery performance.

3. Excessive Carbon Consumption

Due to frequent carbon replacement caused by carbon breakage and loss, the plant faced increased operating costs and required continuous carbon replenishment.

Our Solution

To address these challenges, we provided a customized activated carbon solution specifically designed for gold recovery applications.

High-Performance Coconut Shell Activated Carbon for Gold Mining

We recommended our premium coconut shell activated carbon with optimized physical and adsorption properties:

The high mechanical strength structure allows the carbon to withstand continuous agitation and circulation inside CIP adsorption tanks, significantly reducing carbon breakage and gold loss.

Before full-scale delivery, we provided samples for on-site adsorption testing. After confirming that the performance met the customer's production requirements, the customer approved the solution.

Project Delivery

Following successful testing, we supplied:

• Product: High-strength coconut shell activated carbon for gold extraction

• Quantity: 56 tons full container shipment

• Shipping Port: Xiamen Port, China

• Service Provided: Complete export documentation and international logistics support

The entire supply process was completed smoothly, ensuring stable delivery and production continuity for the customer's gold processing operation.

Project Results

After implementing our activated carbon solution, the customer achieved significant improvements in production performance:

The improved carbon strength reduced fine carbon generation during operation, helping the plant minimize gold loss while maintaining more stable adsorption performance.

Customer Feedback

“The activated carbon performance is stable with much less carbon breakage. It has helped us reduce gold losses and improve production efficiency. The supply process and export documentation were also smooth and professional.”

Long-Term Partnership

Following the successful application of our activated carbon in the Egyptian gold processing plant, the customer continued cooperation through repeat orders.

By providing high-strength activated carbon solutions, technical support, and reliable international supply capability, we helped the customer achieve more stable CIP gold recovery performance and lower operational costs.
