The BF-2.8 is a self-aspirated mechanical flotation machine for copper ore flotation. Its 2.8 m³ cell and closed double-cone impeller provide effective pulp circulation and air dispersion for copper sulfide flotation circuits.

Copper flotation usually includes roughing, scavenging and cleaning stages. The BF-2.8 can serve as a rougher or scavenger cell in copper circuits where self-aspiration and self-pulping operation is preferred, drawing air and pulp without auxiliary pumps.

• Self-aspirated and self-pulping operation for copper flotation circuits.
• Closed double-cone impeller for strong downward pulp circulation.
• High air intake with relatively low power consumption.
• Horizontal arrangement for flexible circuit configuration.
• Suitable for chalcopyrite and other copper sulfide ores.

The motor drives the impeller through a belt drive. The rotating impeller agitates the copper pulp and creates a vacuum that draws air through the suction pipe into the impeller chamber. The air-pulp mixture is dispersed into fine bubbles, and copper mineral particles attach to the bubbles to form mineralized froth for recovery.
