What Is XCF Air Flotation Cell?
XCF flotation machine is an air flotation cell used for mineral separation in flotation plants. Also known as an external air-supplied mechanical flotation cell, it introduces low-pressure air through a blower while the impeller and stator system provide mechanical agitation to create stable bubbles and improve pulp circulation. Unlike self-aspirated flotation cells, XCF flotation cells use an external air supply system while maintaining self-suction slurry capability for continuous flotation operations.
In a complete flotation circuit, XCF flotation machines are commonly combined with KYF flotation machines to form a flotation unit. XCF cells are mainly used as suction-type flotation cells, utilizing their self-suction slurry capability to improve slurry transfer between cells, while KYF cells are typically arranged as downstream direct-flow flotation cells. This combined configuration is widely applied in roughing and scavenging stages for copper, gold, lead-zinc, and other mineral processing plants.If you’d like to learn more, click on “Types of Flotation Cells for Mineral Processing.”
How Does XCF Air Inflation Flotation Cell Work?
XCF air inflation flotation cell separates valuable minerals from gangue by combining external air injection, mechanical agitation, and continuous slurry circulation. During operation, the impeller generates a vertical slurry circulation inside the tank, while low-pressure air supplied by a blower is introduced into the pulp and mixed with slurry to produce stable mineralized bubbles.
The mineralized bubbles rise to the froth layer, where valuable minerals are recovered as concentrate, while unwanted gangue remains in the slurry and is discharged as tailings. With its self-suction slurry capability, the XCF flotation cell can be used as a suction-type cell in flotation circuits and is commonly combined with KYF flotation machines for continuous roughing and scavenging operations.
Main Components
The main components of an XCF flotation machine include the impeller, stator, air distribution system, and self-suction structure. Their design determines the efficiency of air dispersion, slurry circulation, and bubble-mineral contact during the flotation process.

Advantages
XCF flotation cell machine is widely used in medium and large-scale flotation circuits. It adopts an external air supply system and a specially designed impeller structure to maintain slurry circulation and air-pulp mixing during operation. With its self-suction slurry capability, XCF cells can be easily arranged in continuous flotation circuits for copper, gold, lead-zinc, and other mineral processing applications.
Applications
XCF flotation cells are widely used in mineral processing plants for the flotation separation of metallic and non-metallic minerals. They are mainly applied in roughing and scavenging circuits where reliable pulp handling and continuous flotation operation are required. Typical applications include copper, gold, lead-zinc, sulfide minerals, and other ore beneficiation processes.

How XCF and KYF Flotation Machines Work Together?
XCF and KYF flotation machines are commonly combined to form a flotation unit in medium and large-scale mineral processing plants. In this arrangement, the XCF flotation cell is used as a suction-type cell, utilizing its self-suction slurry capability to draw pulp into the flotation circuit, while the KYF flotation machine works as a downstream direct-flow cell for continuous flotation separation.
The XCF-KYF combination allows flotation cells to be arranged in a more flexible layout without complex slurry transfer systems. XCF handles slurry suction at the front section, and KYF continues the flotation process with stable mixing and aeration performance. This configuration is widely used in copper, gold, lead-zinc, and other mineral processing plants where continuous flotation operation is required.
How to Choose the Right XCF Flotation Machine?
Selecting the right XCF flotation machine depends mainly on the flotation process, plant capacity, and ore characteristics. XCF flotation cells are generally selected for medium and large-scale beneficiation plants that require external air supply, stable slurry circulation, and suction-type flotation operation. They are often combined with KYF flotation machines to form continuous flotation circuits.
The machine size should be selected according to the required processing capacity and flotation residence time. Small and medium models are suitable for lower-capacity plants, while large-volume models such as XCF-16, XCF-24, and XCF-38 are commonly used in large flotation circuits with higher throughput requirements.
Ore properties should also be considered during selection, including mineral type, particle size, and slurry conditions. Before finalizing the equipment, the flotation flowsheet, blower system, and installation layout should be evaluated to ensure the selected XCF flotation machine matches the project requirements.
