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.
