Tailings (fine residues in the form of sludge from mining) have traditionally been stored in large sedimentation ponds, creating a significant environmental burden and wasting valuable process water. Under increasingly strict environmental standards, traditional wet stacking methods are no longer sustainable.
Kosun offers modern dewatering solutions to treat mining residues economically, recover process water, and achieve the multiple goals of saving space, reducing costs, and protecting the environment. This article highlights how Kosun uses its core technology—the decanter centrifuge—to address industry pain points and support sustainable mine development.
I. The Challenges and Necessity of Tailings Treatment System
Traditional wet stacking of tailings faces multiple challenges:
Environmental Pollution: Harmful substances can seep into the groundwater.
Safety Hazards: Tailings ponds pose a risk of dam failure, especially in unstable geological regions.
Resource Waste: Process water is difficult to recover, consuming large amounts of fresh water resources.
An efficient and reliable tailings treatment system has become essential infrastructure for modern mines.
II. Kosun Tailings Solution: Core Technology and Process
Addressing the difficulties in tailings slurry treatment, Kosun has developed a comprehensive solution centered on the decanter centrifuge, reducing waste volume and enabling water resource recycling.
Core Equipment:
Decanter Centrifuge: Generates centrifugal force through high-speed rotation to efficiently and continuously separate solid particles from liquid.
Supporting Equipment: Includes screening equipment (for pre-treatment), dosing systems (to improve efficiency), and belt conveyors (to transport the filter cake).
Process Flow:
The system uses a “screening + centrifugal dewatering and dry stacking” process:
Pre-treatment and Separation: Tailings slurry is screened, then pumped to the Kosundecanter centrifuge for solid-liquid separation.
Water Resource Reuse: The separated liquid phase (clean water) is fully returned to the mine’s production processes for recirculation.
Dry Stacking: The solid phase (dry cake) is transported for safe, dry stacking.
III. Key Advantages of the Kosun Tailings Treatment System
The Kosun solution complies with regulatory requirements and provides significant environmental and economic benefits:
Environmental Friendliness: Reduces wastewater volume and pressure on dam walls, minimizing environmental risks.
Cost Savings: Recovers process water, significantly lowering operational costs and fresh water demand.
Continuous Stability: The screw centrifuge runs continuously without filter cloths, ensuring stable, round-the-clock dewatering.
Small Footprint, Easy Installation: Equipment is compact and can be fixed in place or used as a mobile containerized solution.
