The Application of Industrial Filter Cloth in Horizontal Vacuum Belt Filters —— Filtering Solutions for the Feldspar Mica Mining Industry

In the stages of mineral resource development and deep processing, solid-liquid separation is an extremely critical procedure. For non-metallic minerals such as feldspar and mica, their beneficiation and purification processes often involve methods like flotation, magnetic separation, and gravity separation. Meanwhile, during the final stages of concentration, washing, and solid-liquid separation, the selection of filtration equipment and filter cloths directly affects the purity of the finished mineral powder, energy consumption, and production efficiency. In recent years, Horizontal Vacuum Belt Filter With its advantages of continuous filtration, efficient dewatering, and a high degree of automation, it has gradually become the mainstream equipment in the mineral processing industry. And in this process, CitiusS CITIUS Industrial Filter Cloth Playing a decisive role.

I. Challenges in Solid-Liquid Separation in the Mineral Processing Industry

Feldspar and mica are widely used in fields such as ceramics, glass, insulation materials, and refractory products. Particularly with the growth of the new energy and electronics industries, the demands for purity and particle size distribution of feldspar powder and mica powder are becoming increasingly stringent. In the mineral processing and post-treatment stages, the industry currently faces several major challenges:

1. The difficulty in separating fine-grained mineral slurries
   After being crushed and subjected to flotation, the mineral slurry containing feldspar and mica consists of fine particles with a broad size distribution. If the filter cloth pore size is chosen improperly, material leakage or clogging is highly likely to occur.
2. The filter cake has a high moisture content.
   Mica slurry has a flaky structure that easily stacks up to form a dense filter layer, leading to low dehydration efficiency during vacuum filtration and increasing energy consumption in the subsequent drying process.
3. Wear and chemical resistance requirements
   Mineral processing reagents often contain acids, bases, or organic chemicals. During prolonged operation, filter cloths must not only withstand chemical corrosion but also exhibit excellent abrasion resistance, thereby extending their service life.
4. Continuous Production and Stability
   Mining operations typically involve large-scale, long-term continuous processes, so filter cloths must maintain stable performance over extended periods to prevent downtime losses caused by frequent replacements.

II. Advantages of the Horizontal Vacuum Belt Filter Machine

When addressing the issues mentioned above, the horizontal vacuum belt filter ( Horizontal Vacuum Belt Filter, HVBF ) Demonstrates unique advantages:

• Continuous operation : The materials are evenly spread across the filter belt, and vacuum suction efficiently removes water and performs washing—entirely in an automated and highly continuous process.
• Efficient Washing : Suitable for multi-stage washing of feldspar and mica concentrate slurries, ensuring thorough removal of impurities and enhancing the purity of the concentrate.
• Controllable Filter Cake Thickness By adjusting the fabric amount and vacuum level, it is possible to flexibly control the thickness of the filter cake layer, ensuring both filtration efficiency and product quality standards.
• Highly adaptable : Suitable filter cloths can be selected based on the specific characteristics of different slurries, enabling effective retention of fine-particle materials.

But no matter how advanced the filter machine is, it will struggle to deliver its full potential without matching high-performance filter cloth. This is precisely where Citiuss CITIUS industrial filter cloth shines.

III. Citiuss CITIUS Industrial Filter Cloth Solutions

As The drafting unit of the industry standard for industrial filtration materials and filter belts used in belt filter presses CITIUS by Citiuss has accumulated extensive experience in the field of feldspar and mica beneficiation and filtration, enabling it to provide customized filter cloth solutions for mining companies. Its key advantages are primarily reflected in the following aspects:

1.  Precise Aperture Control

The CITIUS filter cloth from Citius utilizes advanced weaving and post-processing techniques to ensure a uniform pore size distribution. This not only enables efficient retention of fine mineral powders but also maintains excellent water permeability, preventing clogging of the filter cloth. For fine particles in feldspar and mica slurries, it delivers ideal solid-liquid separation performance.

2.  Excellent wear resistance and chemical resistance

Targeting the abrasive particles and flotation reagents present in the slurry, the filter cloth developed by Citiuss CITIUS boasts exceptional wear resistance and acid-alkali durability, ensuring long service life even under heavy-load operating conditions.

3.  The filter cake has good release properties.

Mica, a flaky mineral, tends to form a dense layer on the surface of filter cloths. The CITIUS filter cloth from Citiuss features a rationally designed smooth surface, making it easy to detach the filter cake and significantly reducing manual cleaning efforts as well as downtime.

4.  Customized design

CITIUS by Citiuss not only offers standard-specification filter cloths but also provides customized solutions tailored to the characteristics of the slurry and equipment parameters—such as filter cloth thickness, weave style, edge finishing, perforation, and seam techniques—to perfectly align with customers' unique production requirements.

5.  Reduce overall costs

By extending the lifespan of filter cloths, reducing the moisture content of filter cakes, and enhancing filtration efficiency, Citiuss CITIUS helps mining companies cut energy consumption and labor costs, enabling green and highly efficient production.

IV. Application Example: Practical Effects of Feldspar-Mica Filtration

At a large-scale mine, the tailings slurry from feldspar and mica beneficiation previously used ordinary filter cloths, which led to the following issues:

• The filtrate has a high solids content and requires multiple rounds of clarification.
• The filter cloth has a lifespan of less than two months, and frequent replacements negatively impact production capacity.
• The filter cake has a moisture content as high as 25% Above, this increases drying costs.

After switching to the specialized filter cloth designed for the Xadis CITIUS horizontal vacuum belt filter, the situation has noticeably improved:

• The clarity of the filtrate was significantly improved, reducing the need for secondary treatment steps.
• Filter cloth lifespan extended to 6 More than a month, production stability has improved;
• The moisture content of the filter cake is reduced to 18% Right, drying energy consumption has decreased. 20% The above;
• Overall production costs have decreased, product quality has improved, and the company has earned high customer recognition.

V. Future Trends and Green Development

As the mining industry faces increasingly stringent requirements for energy conservation, emission reduction, and green mineral processing, the selection of solid-liquid separation equipment and filter cloths will no longer be limited to “ Filtration Efficiency ” , while placing greater emphasis on End-to-end economic efficiency, environmental friendliness, and intelligent optimization CITIUS at Citiuss is actively developing new filter cloths that are more resistant to high temperatures, highly resistant to chemical corrosion, and equipped with enhanced intelligent monitoring capabilities. Combined with a digital management system, these solutions offer mining companies a one-stop service—from material property analysis to optimized filtration processes.
