Rougher Flotation Machine for Coarse Particle Recovery

Strong pulp circulation helps keep coarse and fast-settling particles suspended during rougher flotation.

The BF-6.0 is a self-aspirated mechanical flotation machine that can be used for rougher flotation duties in mineral processing circuits. Its 6.0 m³ cell volume and strong downward pulp circulation support the recovery of valuable minerals from mineral pulp.

Key Advantages

• Strong Pulp Circulation – The closed double-cone impeller creates strong downward circulation to help keep coarse particles suspended.
• Reduced Coarse Sand Settling – The circulation pattern helps reduce coarse sand accumulation in the flotation cell.
• Self-Aspirated Operation – Air is drawn into the flotation cell through the flotation mechanism without a separate external air supply.
• 6.0 m³ Cell Volume – Suitable for flotation circuits requiring a medium-sized cell volume.
• Horizontal Arrangement – Suitable for multi-cell flotation banks arranged according to the process flowsheet.

Working Principle

The motor drives the impeller to agitate the mineral pulp and create strong downward circulation. The rotating impeller creates negative pressure at its center, drawing air into the impeller chamber. Air and pulp are mixed and dispersed throughout the cell, allowing mineral particles to contact and attach to bubbles before rising to the surface as mineralized froth.

Applications

• Rougher Flotation
• Mineral Processing
• Ore Beneficiation
• Gold Ore Flotation
• Copper Ore Flotation
• Lead-Zinc Ore Flotation
• Mining Flotation Circuits

FAQ

Can the BF-6.0 be used for rougher flotation?
Yes. The BF-6.0 can be used for rougher flotation duties where strong pulp circulation is required.

How does the BF-6.0 handle coarse particles?
Its closed double-cone impeller creates strong downward pulp circulation, which helps keep coarse particles suspended and reduce coarse sand settling.

Does the BF-6.0 require an external air blower?
The BF series is self-aspirated and self-pulping, and the supplied manual states that it does not require a foam pump. 

What is the BF-6.0 capacity?
The listed capacity is 3–6 m³/min with an 18.5 kW motor.
