The XCF flotation machine is a forced-air mechanical flotation cell used in mineral processing. It uses an external blower to supply air and a specially designed impeller system to draw slurry into the cell.

Commonly used in rougher and scavenger flotation, XCF machines can also be combined with KYF flotation cells to meet different process and layout requirements.

The motor drives the impeller, creating slurry circulation and drawing pulp into the lower impeller area. Air supplied by an external blower enters through the air distribution system and mixes with the slurry.

The impeller disperses air into bubbles, while the stator helps direct the slurry-air mixture into the tank. Target mineral particles attach to bubbles and rise to the surface, forming froth that can be collected as concentrate.

Important: XCF can self-aspirate slurry, but it still requires an external blower for air supply.

• External air supply: Air is delivered by a blower and distributed through the machine's air system.

• Self-aspirating slurry: The impeller arrangement draws slurry into the cell, supporting its use as a suction cell.

• Mechanical agitation: The impeller and stator promote slurry circulation and air dispersion.

• Flexible circuit configuration: XCF machines are commonly used for rougher and scavenger duties and can be paired with KYF cells.

Actual performance depends on ore characteristics, operating conditions and circuit design.

Both XCF and KYF are forced-air mechanical flotation machines. Their main difference is slurry-handling capability.

In a combined XCF-KYF circuit, XCF is commonly used as the suction cell and KYF as the direct-flow cell. This arrangement may reduce intermediate pumping requirements under suitable plant conditions. Final selection depends on the flowsheet, installation layout and operating requirements.

Before choosing an XCF flotation machine, consider:

• Ore type: Target minerals, particle size and slurry characteristics.

• Processing capacity: Required throughput and effective flotation volume.

• Flotation stage: Rougher or scavenger duty and required residence time.

• Air supply: Blower capacity and air distribution requirements.

• Maintenance: Impeller, stator and other wear-part inspection and replacement.

The appropriate model and number of cells should be determined from process requirements and, where available, flotation test results.
