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
→ 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

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
• Target cake moisture
• Water-clarity requirement
