Calium Hypochlorate Decanter Centrifuge machine
,Horizontal Decanter Centrifuge
,3 Phase Tricanter Centrifuge
The Decanter Centrifuge for Copper Mine Tailings Dewatering continuously separates mineral solids from tailings water.
It is suitable for copper concentrator tailings, thickener underflow, grinding wastewater, and process-water recovery applications.
- Copper flotation tailings dewatering
- Thickener underflow treatment
- Fine mineral sludge separation
- Concentrator wastewater clarification
- Process-water recycling
- Tailings volume reduction
Abrasive Mineral Solids
Quartz, sand, and metal-bearing particles can cause severe wear.
Fine Particle Size
Fine clay and flotation residues may require flocculant conditioning.
Variable Solids Content
Tailings concentration may change with ore and plant operation.
High Throughput
The centrifuge must balance capacity, cake dryness, and liquid clarity.
Corrosive Process Water
Chlorides, sulfates, and flotation chemicals affect material selection
Copper Mine Tailings Dewatering Solution
Copper Mine Tailings
→ Screening
→ Agitated Feed Tank
→ Optional Flocculant Dosing
→ Decanter Centrifuge
→ Dewatered Solids + Clarified Water
Dewatered Solids → Transport / Backfill / Further Dewatering
Clarified Water → Process Reuse / Further Treatment
Peony Can Provide
- Tailings testing and equipment selection
- Feed tank and controlled pump
- Flocculant dosing system
- Adjustable bowl and differential speed
- Carbide or ceramic wear protection
- PLC and dual-VFD control
- Water and solids collection system
How the Decanter Centrifuge Works
1. Tailings Feeding
Conditioned copper tailings enter the rotating bowl.
2. Solids Sedimentation
Mineral particles move outward and form a solids layer.
3. Liquid Clarification
Separated water remains closer to the bowl center.
4. Solids Conveying
The screw conveyor moves settled solids toward the conical end.
5. Continuous Discharge
Dewatered tailings and clarified water leave through separate outlets.

Main Advantages
Continuous Tailings Dewatering
Processes tailings without batch filtration cycles.
Process-Water Recovery
Returns clarified water to grinding or flotation circuits.
Reduced Tailings Volume
Lowers transport, storage, and disposal requirements.
Heavy-Duty Wear Protection
Protected feed zones, scroll flights, and discharge outlets resist abrasion.
Adaptable Operation
Adjustable bowl speed and differential speed handle changing feed conditions.
Please provide:
- Solids concentration
- Particle-size distribution
- Mineral density
- Required capacity
