Introduction

Recovering fine gold has long been a major challenge in placer mining. Traditional sluice systems perform well for coarse particles but fail to capture micron-sized gold, leading to significant losses. Studies show that up to 30–50% of gold value can remain unrecovered in fine fractions.

What Is Gold Carpet

Gold carpet is a specialized recovery medium designed to capture fine gold particles from slurry flow. Unlike conventional systems that rely on gravity separation, it uses a fiber-based entrapment mechanism to retain particles effectively.

Three-Layer Structure

• Top Layer: High-density polyethylene fibers create a dense capture zone
• Middle Layer: Structural matrix ensures flow stability
• Bottom Layer: Reinforced backing provides durability and anti-slip performance

This multi-layer structure allows efficient interception and retention of gold particles.

Working Principle

When slurry flows across the carpet:

• Light materials remain suspended and move downstream
• Heavy gold particles settle into the fiber matrix
• Multiple capture mechanisms retain particles within the structure

This ensures stable and continuous recovery performance.

Key Advantages

High Recovery Efficiency

Capture rates exceed 90%, including fine particles below 100 microns

Long Service Life

Durable polyethylene materials enable 12–24 months of continuous use

Easy Maintenance

Cleaning requires only water and minimal time

Flexible Application

Available in multiple fiber heights to match different conditions

Applications

• River placer mining
• Tailings reprocessing
• Small-scale mining
• Mill clean-up circuits

Conclusion

Gold carpet technology provides a highly effective solution for fine gold recovery. By improving capture efficiency and reducing losses, it significantly enhances mining profitability and operational performance.
