Filter Press Maintenance for Mining: A Practical Guide

Fri, 28 Aug 2026 10:30:53 +0800

A filter press is widely used for mining tailings dewatering, mineral concentrates, sludge treatment and other solid-liquid separation processes. In demanding mining environments, regular filter press maintenance for mining applications is essential to maintain stable filtration performance, reduce downtime and extend equipment service life.

A proper maintenance program should cover filter cloths, filter plates, hydraulic systems, seals and mechanical components.

Signs Your Mining Filter Press Needs Maintenance

Operators should monitor the equipment for the following warning signs:

Reduced filtration efficiency: Longer filtration cycles, lower throughput or cloudy filtrate may indicate clogged filter cloths or worn components.

Higher filtration pressure: Increasing pressure with reduced performance can indicate blocked cloths, changes in slurry characteristics or equipment problems.

Slurry leakage: Leakage between filter plates may result from damaged filter cloths, worn seals or improper plate alignment.

Abnormal noise or vibration: These may indicate mechanical wear, misalignment or hydraulic system problems.

Frequent shutdowns: Repeated failures are a clear indication that preventive maintenance is required.

Key Mining Filter Press Maintenance Tasks

1. Inspect and Clean Filter Cloths

Filter cloths are essential for effective tailings filtration. Check regularly for tears, excessive wear and mineral deposits. In applications involving abrasive ores or tailings, timely filter cloth replacement can help maintain filtration efficiency and prevent filtrate contamination.

2. Clean Filter Plates

Residual tailings and filter cake can accumulate on filter plates and sealing surfaces. Regular cleaning helps maintain proper plate sealing and stable mining dewatering performance.

3. Check the Hydraulic System

Inspect hydraulic cylinders, hoses, valves and connections for leaks. Make sure the plate-closing pressure remains within the recommended operating range. Stable hydraulic pressure is particularly important for high-pressure filter press applications in mining.

4. Check Plate Alignment and Seals

Correct plate alignment ensures uniform pressure across the filter pack. Inspect sealing surfaces and replace damaged seals promptly to prevent slurry leakage during the filtration cycle.

5. Inspect Structural and Wear Components

Mining slurries can contain highly abrasive particles. Regularly inspect the filter press frame, guide rails, bearings, plate handles and other components for corrosion, deformation and wear.

How Often Should a Mining Filter Press Be Maintained?

A practical maintenance schedule includes daily visual inspections, weekly cleaning and functional checks, and monthly inspections of plates, cloths, seals and hydraulic components. A comprehensive inspection is generally recommended every 3–6 months.

For mining tailings dewatering, copper concentrate filtration, iron ore processing and other abrasive applications, maintenance intervals may need to be shortened according to slurry characteristics and operating conditions.

Following the manufacturer's recommendations and keeping accurate maintenance records can help identify potential problems before they cause costly downtime.

Proper maintenance is the foundation of reliable mining filtration. With regular inspections and timely replacement of wear parts, KERTE filter press systems can deliver stable solid-liquid separation, tailings dewatering and mineral processing filtration performance in demanding mining environments.

Vale Targets Gold & Rare Earths Hidden in Mining Waste

Thu, 27 Aug 2026 10:29:27 +0800

Brazilian mining giant Vale is exploring new ways to extract rare earth elements, gold and other valuable minerals from mining waste, highlighting the growing importance of circular mining and mineral waste recovery. According to a Reuters report published on August 26, 2026, Vale’s research is still at an early stage, but preliminary results have been encouraging.

The initiative is part of Vale’s broader Waste to Value strategy, which aims to reduce waste generation, recover materials from tailings and waste rock, and create additional economic value from resources that were previously considered waste. Vale reported that its circular mining program produced 26.3 million tonnes of iron ore from circular sources in 2025, more than double the 2024 figure. The company sees potential for approximately 10% of its iron ore production to come from circular sources by 2030.

The focus on rare earths is particularly significant as demand continues to grow for critical minerals used in electric vehicles, wind turbines, electronics and defense technologies. At the same time, recovering gold and other minerals from existing tailings can help mining companies maximize resource utilization while reducing the volume of material requiring long-term disposal.

Filtration: An Important Step in Mining Waste Recovery

As mining waste is reprocessed, efficient solid-liquid separation becomes increasingly important. Tailings generated during mineral recovery often contain large amounts of water and fine particles. Filter presses can separate water from mineral solids, producing drier filter cake while allowing recovered process water to be recycled.

This can support several stages of a circular mining operation, including tailings dewatering, water recovery, material handling and preparation for further mineral processing. Vale itself identifies tailings filtration and dry stacking as important technologies for reducing dependence on conventional tailings storage. In 2025, more than 80% of Vale’s iron ore production in Brazil did not depend on dams for tailings storage.

For mining companies investigating the recovery of residual iron, gold, rare earths and other critical minerals, high-efficiency filtration can become an essential link between mineral recovery and responsible waste management.

KERTE Filter Press provides industrial filtration solutions for mining, tailings and mineral processing applications, helping customers achieve efficient dewatering, water recovery and safer handling of mineral residues. As circular mining develops, advanced filtration technology can play a key role in turning mining waste into valuable resources.

Why Does Filter Cloth Break After Just 3 Months? 5 Common Mistakes to Avoid

Thu, 20 Aug 2026 10:14:33 +0800

Filter cloth is one of the most important consumable components in a filter press. However, premature filter cloth damage is often not caused by poor cloth quality alone. Incorrect operating conditions, damaged filter plates, excessive pressure, and improper material selection can significantly shorten filter cloth service life.

Here are 5 common mistakes that can cause filter cloth to fail much earlier than expected.

1. Excessive Feeding Pressure Can Tear the Filter Cloth

Excessive feeding pressure places continuous stress on the filter cloth fibers. When slurry pressure becomes too high, especially with sudden pressure fluctuations, the cloth can be repeatedly stretched and impacted. This may cause cracks, edge damage, or even sudden tearing.

Stable and properly controlled feeding pressure is essential for protecting the filter cloth and maintaining consistent filtration performance.

2. Hard Particles Can Wear Through the Cloth

Sludge containing sand, gravel, metal particles, or other abrasive solids can act like sandpaper against the filter cloth. During repeated filtration cycles, high-hardness particles continuously rub against the cloth surface and gradually wear down the fibers.

For abrasive slurry applications, selecting a filter cloth with suitable strength and wear resistance is critical.

3. Damaged Filter Plates Can Cut the Cloth

A filter cloth can also be damaged by the filter plate itself. Burrs, cracks, sharp edges, or damaged plate surfaces may directly scratch or cut the cloth during operation.

Deformed filter plates can also create uneven pressure distribution, causing excessive local stress. Regular inspection and maintenance of filter plates can significantly reduce this risk.

4. Excessive Pressing Time Accelerates Aging

Long-term compression under high pressure can keep filter cloth fibers in a highly stressed condition. If the pressing cycle is unnecessarily long, the cloth may gradually lose flexibility and become brittle.

Optimizing filtration and pressing cycles according to the material and equipment conditions can help extend cloth service life.

5. The Wrong Filter Cloth Material Can Cause Rapid Failure

Different materials require different filter cloth types. Choosing the wrong material for a specific chemical or temperature environment can result in rapid degradation.

For example, polyester cloth may not be suitable for certain strongly acidic conditions, while strong alkaline or high-temperature applications require carefully selected cloth materials with appropriate chemical and thermal resistance.

How Can You Extend Filter Cloth Service Life?

Longer filter cloth life starts with the right combination of cloth material, slurry characteristics, feeding pressure, filter plate condition, and operating parameters.

At KERTE Filter Press, we provide filter cloth and filter press solutions designed for demanding applications such as mining tailings, concentrates, wastewater, and industrial sludge. Choosing the right filtration configuration can help reduce unplanned downtime, lower replacement costs, and maintain stable filtration performance.

The right filter cloth is not simply a consumable—it is an important part of your filtration system.

Panama's Cobre Panama Copper Mine Moves Closer to Restart

Thu, 30 Jul 2026 10:29:36 +0800

After nearly two years of suspension, Cobre Panama, one of the world's largest copper mines, may soon resume operations. The Panamanian government is considering new partnership models with First Quantum Minerals, marking an important step toward restarting a project that plays a key role in the global copper supply chain.

The mine was shut down in late 2023 after Panama's Supreme Court ruled its long-term mining contract unconstitutional. Public protests over environmental protection and resource management also contributed to the closure. The shutdown significantly affected Panama's economy, reduced employment, and removed more than 1% of global copper production.

Today, changing market conditions are driving a shift in government policy. Strong copper prices, growing demand from renewable energy and electric vehicle industries, and domestic economic pressures have renewed interest in bringing the mine back online.

Officials are currently evaluating two possible operating models. The first would create a state-owned mining company that partners with First Quantum Minerals. Under this plan, the company would continue operating the mine while sharing ownership with the government. The second option would allow the government to retain ownership of the mining rights while leasing the operation to First Quantum, a model already used in several resource-rich countries.

To prepare for a potential restart, the government has approved the sale of previously mined copper concentrate, authorized the restart of the mine's power plant, and completed an environmental audit. A final decision is expected before the end of the year.

The restart of Cobre Panama could strengthen global copper supply at a time of increasing demand. However, long-term success will depend on maintaining strict environmental standards, effective tailings management, and transparent cooperation between mining companies, governments, and local communities.

For modern mining operations, efficient solid-liquid separation is essential. Advanced filter press systems help reduce tailings moisture, recover valuable process water, and improve environmental compliance. As copper producers continue to invest in sustainable mining practices, reliable filtration equipment will play an increasingly important role in supporting productivity, lowering operating costs, and meeting environmental requirements.

Chile Delays Maricunga Lithium Project to 2034

Thu, 23 Jul 2026 10:41:49 +0800

Chile’s lithium sector has entered a new phase after state-owned mining company Codelco announced that production at its flagship Maricunga Lithium Project will now start in 2034, four years later than the previous 2030 target. As one of the country’s most important battery metal developments, the delay is likely to affect global lithium supply expectations, investment timing, and long-term mining plans across South America.

Chile remains one of the world’s leading lithium producers because of its rich salt lake resources. For years, production has been dominated by major international players such as SQM and Albemarle. To strengthen national participation, the Chilean government introduced its National Lithium Strategy, encouraging state-owned companies to work with global mining firms while keeping tighter control over strategic mineral assets.

Maricunga is a central project in this strategy. Earlier this year, Chile revised Codelco’s operating agreement for lithium development, further confirming the project’s strategic importance. Codelco has also partnered with Rio Tinto to advance the project, highlighting the growing role of international cooperation in Chile’s evolving lithium industry.

At the same time, the updated timeline reflects one of the biggest challenges for mining investment in Chile: long approval cycles. Compared with many mining regions in Australia or Africa, new projects in Chile must pass detailed environmental reviews, regulatory procedures, and community consultations before construction can begin. These steps often extend development schedules and delay new capacity from reaching the market.

For the global lithium market, the postponement may have mixed effects. In the medium term, slower output growth from Maricunga could reduce the pace of new supply between 2030 and 2034, easing oversupply concerns and offering some support to lithium prices. Established producers may also retain their market positions for longer, while new entrants face more extended development periods.

As demand for electric vehicles and energy storage continues to rise, mining companies are focusing more on resource recovery, cost control, and environmental performance throughout mineral processing.

Efficient solid-liquid separation is now a critical part of lithium production. High-performance filter press systems help recover process water, reduce tailings moisture, lower transport costs, and improve sustainable water management, especially in water-scarce regions such as South America’s lithium salt lakes.

KERTE Filter Press delivers reliable dewatering solutions for lithium concentrate, tailings, and industrial wastewater. With advanced automatic filter press technology, high water recovery efficiency, and low cake moisture, KERTE helps lithium producers improve efficiency while supporting responsible and sustainable mining development.

Filter Press Working Principle: Efficient Solid-Liquid Separation Solution by KERTE

Thu, 16 Jul 2026 15:26:56 +0800

A filter press is one of the most effective solid-liquid separation technologies widely used in mining, wastewater treatment, chemical processing, food production, and other industries. By applying pressure filtration, a filter press separates liquid from solid particles, reduces sludge volume, and produces a drier filter cake for disposal, recycling, or further processing. As an experienced filter press manufacturer, KERTE provides reliable filtration equipment designed for high-efficiency dewatering applications.

How Does a Filter Press Work?

The working principle of a filter press includes four main stages: filling, filtration, cake compression, and discharge.

During the filling stage, slurry containing solid particles and liquid is pumped into chambers formed between filter plates. The feed pump ensures continuous and uniform slurry distribution inside the press.

In the filtration stage, hydraulic pressure forces liquid to pass through filter cloths while solid particles remain on the cloth surface. The filtered liquid flows through drainage channels and can be collected for reuse or treatment. As solids accumulate, a filter cake is gradually formed inside the chambers.

The compression stage improves dewatering performance. Advanced membrane filter presses use flexible membrane plates to apply additional pressure, squeezing more water from the filter cake and achieving lower moisture content. This process helps reduce transportation and disposal costs.

During the discharge stage, the filter plates open, and the dewatered filter cake is released automatically or manually. The equipment then starts a new filtration cycle.

Types of Filter Presses

KERTE offers various filter press solutions for different industries:

Plate and Frame Filter Press:
