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
