3 stage crushing to reduce ore size below 10 mm

Smart Circular Flotation System:

Intelligent rougher flotation with real-time froth image analysis and reagent dosage control
2 stage cleaner + 2 stage scavenger flotation in closed-circuit configuration
Tailings slurry recycling system with thickener underflow re-pulping and return to head of flotation
Process water recirculation rate >85%，reducing freshwater consumption

Tailings management:

2 stage grinding with hydrocyclone classification to achieve 75 μm (D80)

Concentrate dewatering:High-rate thickener + ceramic disc filter

Key Features of Smart Circular Flotation System:

flotation control system adjusts air flow, pulp level, and reagent addition in real time
Closed water circuit with integrated treatment unit minimizes environmental impact
Tailings slurry recycling enhances copper recovery and reduces reagent consumption
Remote monitoring and predictive maintenance via IoT platform
Energy-saving design with variable speed drives on pumps and agitators
