As the Philippines cements its position in the global minerals market, the need for advanced refining technologies is growing more important.
The Eriez Dry Vibrating Magnetic Filter (DVMF), a high-intensity magnetic separator designed to remove ultra-fine iron-bearing contaminants, is emerging as an essential technology for producers working with lithium, silica, talc, ceramics, and other finely divided industrial minerals and chemical products.
Across the Philippines, local processors are advancing from raw mineral extraction to value-added production. As export markets demand higher standards, achieving contaminant control to parts-per-billion levels has become vital.
The DVMF accomplishes this by combining a high-intensity electromagnet with a flux-converging matrix that generates hundreds of high-gradient collection zones.
As powders flow vertically through the unit, magnetic particles are captured while clean material continues through to discharge. Dual vibratory drives maintain consistent product movement, even with ultra-fine materials, ensuring throughput and stability.
Lithium and Hard-rock Mining
In lithium processing, the DVMF eliminates microscopic contaminants that would otherwise compromise battery-grade material quality.
“The DVMF is perfect for both lithium producers and users,” explains Jose Marin, Director of Mining & Minerals Processing at Eriez-USA. “Producers pulverize lithium before it goes to the user as a very fine powder. DVMF units are placed before and after mill processing.”
Marin noted that “as an additional check, many users position the DVMF at the point they receive lithium purchased from their producer.”
In industrial ceramics and glass production, it safeguards precision and surface integrity, ensuring locally produced materials meet international specifications.
For hard-rock mining operations, integrating Eriez separation systems — suspended electromagnets, metal detectors, and DVMFs — creates a complete line of defense.
“When it comes to hard-rock mining, the best practice among operators is to install equipment to protect crushers and belts,” Marin said. “They accomplish this by combining suspended electromagnets (SEs) and metal detectors.”
“The belt magnet removes ferrous material as it passes under a magnet on a belt or vibratory conveyor, while a metal detector identifies ferrous metals missed by the SE and all nonferrous metals. This is an important preparation procedure as the fine powders move to the DVMF.”
Removing ferrous debris early in the process protects crushers and conveyors, while DVMFs perform final-stage purification. This layered approach aligns with world best practice in mineral handling and quality assurance.
The DVMF’s automated controls and simplified cooling system make it a robust choice for both established plants and new facilities. Units are available in multiple diameters, handling a wide range of feed rates with consistent results.
Eriez’s 5,000-gauss systems routinely reduce contamination from parts-per-million to parts-per-billion levels — an achievement that directly enhances competitiveness on the world stage.
