Tailings Slurry
Tailings slurry is generated during mineral processing and typically contains fine solid particles with a high water content. Depending on the material characteristics, it can also be abrasive and corrosive.
When wet tailings enter a tailings storage facility without sufficient dewatering, they occupy more storage volume and may increase the risk of leakage and contamination. Therefore, effective dewatering helps reduce the volume of tailings and the associated storage requirements.
KOSUN Tailings Dewatering System uses screening and centrifugal separation to process the slurry. First, the screening stage removes coarse particles. Next, centrifugal dewatering separates fine solids from the liquid phase and reduces the moisture content of the tailings.
As a result, the dewatered solids can be prepared for dry stacking or further handling, while the separated water can be recovered and recycled for reuse where suitable.
Tailings Dewatering Solution
KOSUN integrates vibrating screening and decanter centrifugation to provide a continuous tailings dewatering solution.
First, the vibrating screen performs front-end screening and pretreatment. It removes coarse sand, gravel, and other larger particles from the tailings slurry before the centrifugal dewatering stage. This helps reduce the load on downstream equipment and provides stable feed conditions.
Next, the decanter centrifuge performs solid-liquid separation and deep dewatering. High-speed centrifugal sedimentation separates fine tailings particles from the liquid phase and reduces the moisture content of the dewatered solids.
In addition, the system uses a modular layout and PLC-based control. An automatic centrifuge cleaning function also supports continuous and stable operation.
Through the combined screening and centrifugal dewatering process, the system reduces tailings volume, prepares dewatered solids for dry stacking or further handling, and enables recovery of separated water for recycling and reuse where suitable.
Main Equipment
