October 26, 2026 | Xi’an, China
A customized 40 m³/h tailings dewatering and reduction system developed for a Russian mining project successfully passed factory acceptance testing on October 26, 2026. The Russian client visited KOSUN’s manufacturing facility in Xi’an to witness equipment testing, integrated commissioning, and performance verification before delivery.
The successful acceptance demonstrates the system’s ability to meet the project’s technical requirements for tailings treatment, dewatering, and volume reduction.
01. Factory Testing and Performance Verification
Prior to testing, the technical teams from both parties held a coordination meeting to establish the testing conditions, inspection procedures, and acceptance criteria.
The system was then operated under integrated testing conditions, with each treatment stage inspected throughout the process, including material feeding, shale shaker screening, classification, solid-liquid separation, and final discharge.
The inspection focused on operating stability, treatment effectiveness, and key performance parameters. Following a comprehensive review of the test results, all tested parameters met the agreed acceptance standards. The Russian client highly recognized the system’s operating performance, and the acceptance documents were signed on site.
02. Three-Stage Tailings Separation Process
Tailings slurry treatment requires effective solid-liquid separation to reduce the moisture content of discharged solids and improve the recovery of valuable materials.
For this project, KOSUN developed a customized treatment solution based on the characteristics of the client’s materials. The system integrates shale shaker screening with two-stage decanter centrifuge separation, forming a three-stage treatment process.
The main equipment configuration includes:
- LS608 Dewatering Shale Shaker
- LW750 Low-Speed Decanter Centrifuge
- LW650 High-Speed Decanter Centrifuge
The combined process enables progressive separation and dewatering, helping reduce the moisture content of final discharged solids while improving the recovery of useful materials.
03. Key Advantages for Mining Tailings Treatment
Effective Dewatering and Volume Reduction
The integrated separation process helps reduce the moisture content of discharged tailings, contributing to a reduction in the volume of material requiring further handling and disposal.
Improved Material Recovery
Through multi-stage solid-liquid separation, the system supports the recovery of valuable solid materials and improves overall material utilization.
Modular and Customized Design
The modular layout simplifies transportation, on-site installation, and routine maintenance. Equipment configuration can be adjusted according to material characteristics and project-specific operating conditions.
Adaptability to Mining Environments
Designed for demanding outdoor conditions in Russian mining areas, the system is suitable for tailings slurry treatment and dewatering applications involving different types of mineral residues. Its configuration also takes applicable local environmental requirements into consideration.
04. Successful Acceptance and Next Steps
The system passed the factory acceptance test on the first inspection, with all tested performance parameters meeting the agreed requirements. Following the on-site signing of acceptance documents, the project officially entered the delivery stage.
KOSUN’s technical team will continue to coordinate equipment shipment and on-site installation services to support the successful commissioning of the project.
Supporting More Efficient Tailings Management
Effective tailings dewatering and volume reduction play an important role in improving mining waste management and material utilization. Through customized solid-liquid separation solutions and integrated treatment equipment, KOSUN continues to support mining operations in improving tailings treatment efficiency and reducing the volume of material requiring further handling.
