What Is a BF Flotation Cell?
A BF Flotation Cell (BF Flotation Machine) is a self-aspirated mechanical flotation machine used for mineral separation through froth flotation. It consists of a tank body, impeller, stator, transmission system and air intake system. During operation, the rotating impeller generates negative pressure, drawing air and slurry into the mixing chamber to create a uniform air-slurry mixture.
The fine bubbles produced during mixing attach to target mineral particles and rise to the surface to form froth, while unwanted materials remain in the slurry. By combining air suction, slurry agitation and flotation functions in one unit, the BF flotation cell enables stable operation in various mineral beneficiation processes.If you’d like to learn more, click on “Types of Flotation Cells for Mineral Processing.”
How Does BF Flotation Cell Work?
A BF Flotation Cell works by using impeller-driven mixing to combine slurry, air and flotation reagents, allowing valuable minerals to attach to bubbles and separate from the slurry. The flotation process mainly includes slurry mixing, bubble mineralization and froth recovery.If you want to learn more, click “What is a Flotation Cell?”
Slurry Mixing and Air Intake
The impeller creates a suction effect during rotation, drawing air through the air intake system and mixing it with the slurry inside the cell. The strong agitation ensures uniform contact between air, slurry and flotation reagents.
Bubble Generation and Mineral Attachment
The air is dispersed into fine bubbles by the impeller. Target mineral particles attach to the bubbles under the action of flotation reagents and rise with the bubbles to the froth layer, while gangue particles remain in the slurry.
Froth Collection and Mineral Recovery
The mineralized froth overflows or is removed from the surface as concentrate, while the remaining slurry is discharged as tailings. This continuous process enables the recovery of valuable minerals in flotation circuits.
Main Components of BF Flotation Cell
A BF Flotation Cell is composed of several key components designed for slurry circulation, air dispersion and flotation operation. The main components include the impeller and stator system, tank body, transmission system and air intake system.
