The SF Series Flotation Machine is a self-aspirating mechanical flotation machine designed for mineral processing and flotation separation. It combines mechanical agitation, self-air suction and self-slurry suction in one flotation cell. The backward-inclined double-sided impeller provides effective pulp circulation and air dispersion.
With cell volumes from 0.15 to 20 m³, the SF series is suitable for the flotation of non-ferrous metals, ferrous metals and non-metallic minerals, particularly for roughing and scavenging operations.
When the impeller rotates, slurry in the upper and lower impeller chambers is thrown outward by centrifugal force, creating a negative-pressure zone. Slurry enters the upper impeller chamber through the circulation openings in the cover plate, while slurry below the impeller flows toward the center, forming upper and lower circulation loops.
Air is drawn through the intake pipe and central tube into the upper impeller chamber, where it mixes with the slurry. The rotating impeller disperses the air into fine bubbles throughout the flotation cell. Hydrophobic mineral particles attach to the bubbles and rise to the froth layer. The mineralized froth is then discharged by the scraper.

Final equipment configuration should be confirmed according to the selected model and process requirements.
SF flotation machines are suitable for flotation separation of: Non-Ferrous Metal Ores • Ferrous Metal Minerals • Non-Metallic Minerals
They can be used in roughing and scavenging circuits in medium and large mineral processing plants.
The SF flotation machine uses the negative pressure generated by the rotating impeller to draw air into the flotation cell automatically. Unlike forced-air mechanical flotation machines that use an external air supply for aeration, the SF series combines self-air suction, self-slurry suction and mechanical agitation.
The appropriate flotation type should be selected according to ore characteristics, processing capacity and flotation circuit requirements.
For flotation machine selection, the following information is recommended: Ore Type • Processing Capacity • Feed Particle Size • Pulp Conditions • Flotation Stage
Y&X Beijing Technology Co., Ltd. can provide flotation equipment selection and configuration support according to specific mineral processing requirements.
