From successful field testing to full-scale commissioning, GN Solids Control has achieved another milestone in the global mining industry. Five GN GNLW764-VFD variable-frequency decanter centrifuges have been successfully commissioned and are now operating reliably at a major overseas mine tailings slurry separation project.
Located at an altitude of approximately 4,500 meters above sea level, the mine presents exceptional challenges for separation equipment. High-altitude conditions, large slurry volumes, hard mineral particles, and severe abrasive wear all demand reliable equipment design and consistent separation performance.

Proven Performance Earns Customer Confidence
The project was awarded through a highly competitive international tender with stringent technical and qualification requirements. To demonstrate equipment performance under actual operating conditions, GN initially supplied one GNLW764-VFD decanter centrifuge for field testing.
During an extended period of operation, the pilot unit demonstrated stable performance, satisfactory separation results, energy-efficient operation, and a low incidence of equipment failures, according to project feedback.
Impressed by the field results, the customer subsequently placed an additional order for four identical centrifuges, bringing the total project quantity to five units.
This step-by-step cooperation reflects the value of real-world equipment validation in demanding mining applications.

Engineered for High-Capacity Tailings Treatment
The GN GNLW764-VFD features a 30-inch-diameter centrifuge bowl and a variable-frequency drive system, allowing operating parameters to be adjusted according to slurry characteristics and process requirements.
For highly abrasive mineral slurry, wear resistance is particularly important. GN incorporates optimized material selection and wear-resistant design enhancements to help extend component service life and support continuous operation.
The variable-frequency configuration also offers operational flexibility, helping the customer balance separation performance, throughput, and energy consumption.
An Integrated Separation Solution
Beyond the five decanter centrifuges, the supplied system includes a 6,000-liter automatic chemical dosing unit and dedicated screw pumps, forming an integrated tailings slurry treatment solution.
The coordinated system supports chemical conditioning, controlled slurry feeding, and continuous solid-liquid separation. By efficiently separating liquid and solids, it helps improve tailings management, facilitate water recovery, and support the customer’s environmental treatment objectives.

Advancing Mining Separation Technology
From international tender qualification to pilot testing and successful commissioning, this project demonstrates GN Solids Control‘s engineering capabilities, customization expertise, and commitment to reliable equipment performance.
GN will continue to provide practical, high-performance separation solutions that help mining operators improve productivity, manage operating costs, and advance more sustainable mineral processing operations.
