  • Filter cloth for filter press, plate and frame filter press, gold smelting
    Filter type: Plate and frame filter press
    Application industry: Gold smelting


Key applications and selection points of filter cloth for plate and frame filter press in gold smelting

In the entire process of gold smelting, solid-liquid separation is one of the core links to ensure gold recovery rate and production efficiency. With the tightening of environmental protection policies and the increasing demand for comprehensive resource utilization, more and more metallurgical enterprises have begun to pay attention to the filter press process “ Filter cloth ” Selection and application. Among them, Plate and frame filter press Due to its strong pressing force, stable operation, and wide adaptability, it is widely used in the solid-liquid separation process of the gold smelting field. As a core component of the filtration system, Filter press filter cloth The performance is directly related to the filter cake quality, filtration speed, water content, and filtrate cleanliness.

I. Why use plate and frame filter press in gold smelting?

In the gold smelting process, the cyanide leaching method, carbon pulp method, or gravity separation process is often used. These processes generally produce slurries and smelting tailings containing a large number of fine particles. The plate and frame filter press, through high-pressure pressing and closed filtration, can efficiently separate solid particles and solutions, and is widely used in the following processes:

  • Cyanide tailings filtration and dehydration;
  • Recovery of smelting residue filter cake;
  • Pre-dewatering treatment of gold concentrate slurry;
  • Clarification and recovery of tailings for reuse.

Compared with vacuum filter presses, plate and frame filter presses have the advantages of strong pressing force, high filter cake dryness, and good filtrate clarity, making them more suitable for the treatment of high-concentration and high-density metallurgical slurries.

II. Technical requirements of filter press filter cloth in the metallurgical industry

When using plate and frame filter presses in gold smelting, the filter cloth must meet the following key requirements:

  1. Excellent alkali resistance
    In the cyanide process, the slurry is mostly strongly alkaline, which puts high demands on the filter cloth's resistance to chemical corrosion.
  2. Excellent retention performance
    The particle size in gold slurry is extremely small, and the filter cloth needs to have a small pore size and precise weaving to ensure effective retention of precious metal particles.
  3. Good cake release and strength
    The filter cake is easy to fall off after filtration, which helps to shorten the cake cleaning cycle and improve automation efficiency. At the same time, the filter cloth needs to have high tensile strength and be不易变形特性, to adapt to frequent pressing and cleaning.
  4. Customizable size and processing technology
    According to different specifications of plate and frame filter presses, the filter cloth must provide precise size cutting, edging, sewing, and feed hole opening customization services.

III. Application example: Plate and frame filter press + Special filter cloth to improve gold smelting efficiency

Taking a large gold mine smelting plant as an example, it uses Plate and frame filter press for cyanide slag dehydration treatment After using Xiamen Citius (Xiamen Citius) Custom-developed high-strength alkali-resistant filter cloth, the following effects are achieved:

  • The gold content in the filtrate is significantly reduced, and the gold recovery rate is increased 0.5% above;
  • The moisture content of the filter cake is reduced from the original 36% Reduced to 28%；
  • The service life of the filter cloth is extended to the original 1.6 times;
  • Automatic cake release is smooth, equipment operation efficiency is improved, and manual intervention is reduced.

This fully illustrates: Choosing the right filter cloth is equivalent to improving the efficiency and economy of the entire filtration process.

IV. Filter cloth selection suggestions and supporting services

For common application scenarios of plate and frame filter presses in the gold smelting industry, it is recommended to prioritize filter press filter cloths with the following characteristics:

  • Structure: Double-layer or multi-layer fabric structure, combining filtration accuracy and strength;
  • Material: Alkali-resistant material;
  • Processing: Edging anti-tear treatment, reinforced stitching, precise positioning hole opening;
  • Customization: Customizable according to plate and frame size, feeding method, and process parameters.

Xiamen Citius (Xiamen Citius) Filter Materials Technology Co., Ltd. has focused on the industrial filter cloth field for more than 30 years and has rich experience in serving the metallurgical industry. We not only provide high-performance filter cloth products, but also assist enterprises in optimizing filtration systems and improving overall operational efficiency and product quality.

V. Conclusion

In the gold smelting industry, which is extremely sensitive to recovery rate and environmental protection standards, the selection of filter press filter cloth is by no means a trivial matter. High-performance filter cloth suitable for plate and frame filter presses is the key to ensuring the efficient and stable operation of the filtration process. Through reasonable selection and professional matching, not only can operating costs be reduced, but it can also help enterprises win in the fiercely competitive mining market “ Gold ” Beneficial future.
