The Key Role of Industrial Filter Fabrics in Mining and Selection Guide — Yushai Filtration

In modern mining operations, slurry, wastewater, and dust are inevitable by-products. Efficient filtration systems are not only critical for production efficiency but also directly impact environmental protection and safety management. As a core material in these systems, industrial filter fabrics play a vital role. Yushai is dedicated to providing high-performance filter fabrics to help mining operations achieve efficiency, stability, and sustainability in both concentrate and tailings processing.

Core Applications of Filter Fabrics in Mining

1. Mineral Processing
   Filter fabrics separate valuable minerals from slurry, ensuring high recovery rates, minimizing material loss, and enhancing yield, while maintaining stable filtration performance.

2. Tailings Management
   Tailings contain high moisture and potentially harmful substances. Belt filter cloths and pressure filter fabrics help dewater tailings, reduce disposal costs, and minimize environmental risks.

3. Dust Control
   Dust generated during mining affects air quality and poses health hazards. Baghouse filters and high-temperature, wear-resistant fabrics efficiently capture dust, improving workplace safety.

4. Water Recovery and Treatment
   Filter fabrics enable recycling of process water, increasing water-use efficiency and reducing environmental impact.

5. Chemical Processing
   Mining processes often involve acids, alkalis, or solvents. Chemically resistant fabrics, such as PTFE or customized chemical filter cloths, ensure safe and efficient filtration while extending fabric life.

Common Filter Fabric Types and Applications

Tip: Concentrate filtration requires higher separation precision — nylon monofilament or plain weave polyester is preferred. Tailings processing demands wear and chemical resistance — PP or blended fabrics are ideal.

Key Factors Affecting Service Life and Filtration Efficiency

• Fiber Diameter & Filament Count: Thicker filaments → better wear resistance but lower porosity → slower filtration; higher filament count → finer separation but more prone to clogging.

• Fabric Weight (g/m²): Heavier fabrics → longer life but slightly higher filtration resistance.

• Porosity / Openness: High porosity → faster filtration but lower particle retention; low porosity → finer separation but easier clogging.

• Chemical Resistance: Fabrics must withstand long-term exposure to slurries without degradation.

• Wear Resistance: High abrasive tailings require wear-resistant fabrics.

• Pressure Differential (ΔP) Capacity: High-pressure filtration requires fabrics with strong pressure resistance.

Typical Selection Guide for Concentrates and Tailings

Operational Advice: For concentrates, prioritize pore uniformity and separation precision. For tailings, focus on wear resistance, chemical resistance, and cleanability. Actual selection should be adjusted based on slurry particle size distribution, solids content, and pH.
