XJK Flotation Cell/Machine

Mechanical Agitation Self-Aspiration Flotation Equipment for Mineral Processing

XJK Flotation Machine, also known as XJK Flotation Cell, is a classic mechanical agitation flotation equipment widely used in mineral beneficiation plants for the separation of valuable minerals from gangue. With its self-aspiration function and efficient impeller-stator system, the XJK series flotation cell provides reliable performance for recovering metals such as gold, copper, lead, zinc, nickel, and other non-metallic minerals.

As a traditional mechanical agitation flotation machine, the XJK flotation cell integrates slurry mixing, air absorption, and mineral flotation into one unit. The equipment can automatically inhale air and slurry during operation without requiring an external blower, making it suitable for small and medium-scale mineral processing plants as well as various laboratory and industrial flotation circuits.

The XJK series is commonly applied in roughing, scavenging, and cleaning operations where stable mineral recovery and flexible process configuration are required. Due to its simple structure, easy operation, and low maintenance requirements, it remains one of the most widely adopted flotation machines in global mining industries.

Working Principle of XJK Flotation Cell

The XJK flotation machine works based on the interaction between mechanical agitation, air dispersion, and mineral surface properties.

During operation, the motor drives the impeller to rotate at high speed, creating a strong centrifugal force inside the flotation tank. The rotating impeller generates negative pressure, allowing the machine to automatically draw air through the suction pipe while simultaneously circulating the mineral slurry.

The high-speed rotating impeller disperses air into fine bubbles and evenly mixes them with the ore slurry. Valuable mineral particles attach to the air bubbles due to differences in hydrophobicity and float upward to form a stable mineralized foam layer. The froth is then collected through the overflow system, while unwanted gangue minerals remain in the slurry and are discharged.

This efficient air-slurry-mineral interaction improves flotation selectivity and enhances valuable mineral recovery.

Applications of XJK Flotation Machine

The XJK Flotation Cell is widely used in mineral processing plants, mining operations, and beneficiation projects worldwide.

It is suitable for the flotation separation of:

Gold Ore Flotation

XJK flotation machines are widely used in gold beneficiation plants for recovering fine gold-bearing minerals associated with sulfide ores. The self-aspiration flotation design provides stable bubble generation and improves gold recovery efficiency.

Copper Ore Flotation

For copper sulfide ore processing, the XJK flotation cell can be arranged into roughing, scavenging, and cleaning circuits to achieve efficient copper concentrate production.

Lead-Zinc Ore Flotation

The equipment is commonly used in polymetallic ore beneficiation, including lead-zinc separation, where selective flotation performance is required.

Non-Metallic Mineral Flotation

The XJK flotation machine can also process minerals such as:

• Graphite
• Fluorite
• Phosphate
• Quartz
• Feldspar
• Talc

It is suitable for applications requiring effective mineral separation and concentrate upgrading.

Key Advantages of XJK Mechanical Agitation Flotation Machine

1. Self-Aspiration Flotation Design

The XJK flotation cell adopts a self-aspiration structure that automatically absorbs air and slurry during operation. Compared with forced-air flotation machines, it reduces the requirement for additional air supply equipment and simplifies plant layout.

2. Efficient Impeller and Stator System

The optimized impeller and stator structure provides strong slurry circulation and uniform air dispersion. Fine bubbles improve mineral-bubble contact efficiency, supporting higher recovery rates.

3. Reliable Mineral Recovery Performance

The stable flotation environment helps maintain consistent concentrate quality and recovery performance, making it suitable for continuous mineral processing operations.

4. Wear-Resistant Components

Key wearing parts, including the impeller and stator, can be manufactured with wear-resistant rubber or polyurethane materials to extend service life under abrasive mining conditions.

5. Flexible Flotation Circuit Configuration

Multiple XJK flotation cells can be combined into flotation banks for roughing, scavenging, and cleaning stages according to different mineral processing flowsheets.

Structure Features

The main components of XJK Flotation Machine include:

Flotation Tank

The tank provides sufficient residence time for mineral particles and air bubbles to complete flotation separation.

Impeller

The rotating impeller creates turbulence, mixes slurry and air, and ensures uniform particle suspension.

Stator

The stator controls slurry circulation and improves bubble dispersion efficiency.

Drive System

The motor and transmission system provide stable rotational speed for continuous operation.

Froth Collection System

The overflow mechanism collects mineralized froth and transfers concentrate for further processing.
