Tailings Gold Felt: The Ultimate Guide for Mineral Processing Engineers & Plant Managers


In the competitive world of mineral processing, recovering fine gold particles from tailings has long been a challenge—until now. Tailings gold felt (also known as beneficiation felt conveyor belts) has emerged as a game-changing solution for artisanal miners, small-scale operators, and large processing plants across Africa and Southeast Asia. This comprehensive guide examines the technology’s benefits, performance metrics, and how ANNILTE’s premium felt belts can increase your gold recovery rates by up to 70%.


What Is Tailings Gold Felt?

Tailings gold felt is a specialized conveyor belt engineered for gravity separation and mineral beneficiation, particularly in alluvial gold mining and hard rock tailings recovery operations. Unlike standard conveyor belting, this felt belt serves a dual purpose: transporting material while simultaneously trapping and retaining high-density mineral particles.

Core Benefits of Using Felt Belts for Gold Recovery

1. Superior Recovery Rates

ANNILTE’s tailings gold felt has demonstrated the ability to increase beneficiation rates by over 70% compared to traditional methods. This improvement stems from:

  • Advanced needle-punching technology that creates a high-density, porous surface
  • Seamless skirt design preventing material leakage or “run-off”
  • Optimized slow S-curve configuration enhancing ore retention

2. Exceptional Durability and Wear Resistance

The bottom layer of ANNILTE’s tailings gold felt uses imported virgin rubber from the Netherlands, offering:

  • Superior flexibility and aging resistance
  • Hydrolysis resistance for wet processing environments
  • Extended service life that significantly reduces replacement frequency and operational costs

Additionally, the felt layer can be reactivated and reused up to twice, maximizing your investment.

3. High-Temperature and Corrosion Resistance

Mining environments are harsh, but tailings gold felt withstands:

  • High temperatures during ore transportation
  • Chemical corrosion from processing reagents
  • Abrasion from sharp mineral particles

4. Precision Screening

The exceptional softness of ANNILTE’s felt allows for precise screening of non-ferrous metals, effectively filtering out impurities like sand and silt while retaining valuable minerals.


Industry Applications

African Mining Operations

Across Africa’s gold-rich regions, processing plants face the challenge of declining ore grades and increasing tailings volumes. Tailings gold felt enables operators to:

  • Retrofit existing sluice systems for enhanced recovery
  • Process tailings dams for residual gold extraction
  • Increase throughput without expanding plant footprint

Southeast Asian Artisanal & Small-Scale Mining

In countries like Indonesia, the Philippines, and Myanmar, the tailings gold felt technology is gaining traction because it:

  • Requires minimal technical expertise to operate
  • Has low capital investment compared to cyanidation or intensive gravity circuits
  • Enables rapid deployment in remote locations

Beyond Gold

While tailings gold felt is most commonly associated with gold recovery, its applications extend to tungsten, tin, molybdenum, copper, iron, manganese, lead, titanium, and tantalum-niobium ores.
