Self-Aspirating Flotation Cell Without an Air Blower

Self-aspirating by design — no air blower, no extra piping, no added power.

The BF-4.0 is a self-aspirated mechanical flotation machine for lead-zinc and polymetallic sulfide ore flotation. Its 4.0 m³ cell supports stable pulp circulation during sequential lead and zinc flotation.

Flotation of Lead-Zinc Ores

Lead-zinc ores are usually treated by sequential or differential flotation, where galena and sphalerite are separated in successive stages. The BF-4.0 provides consistent agitation and air dispersion across these stages, helping maintain stable froth conditions between the lead and zinc circuits.

Design Advantages

• Sufficient cell volume for polymetallic flotation stages.

• Self-aspiration and self-pulping reduce auxiliary equipment.

• Strong downward circulation keeps dense sulfide pulp in suspension.

• Adjustable pulp level for stage control.

• Can be grouped in banks for lead-zinc flotation lines.

Process Notes

For lead-zinc circuits, the number and arrangement of BF-4.0 cells should be set according to flotation test results and the plant flowsheet, and the pulp level can be adjusted manually or automatically.

FAQ

Is the BF-4.0 suitable for lead-zinc ore flotation?

Yes. It is suited to lead-zinc and polymetallic sulfide flotation circuits.

Can it handle dense sulfide pulp?

Yes. The closed double-cone impeller maintains strong downward circulation to keep sulfide pulp suspended.

What cell volume does the BF-4.0 offer?

The BF-4.0 has a 4.0 m³ cell volume with a listed capacity of 2–4 m³/min.
