SF Flotation Cell/Machine

Product Overview

SF Series Self-Aspiration Flotation Cell is a widely used mechanical agitation flotation machine designed for mineral separation and beneficiation processes. It is mainly applied in the recovery of valuable minerals from sulfide ores, non-ferrous metals, ferrous metals and non-metallic minerals.

As a professional mining flotation equipment, the SF flotation cell integrates slurry agitation, air absorption, mineralization and froth separation into one unit. With its unique self-suction structure, the machine can automatically absorb air and slurry without additional air supply equipment, reducing investment costs and simplifying the flotation plant layout.

The SF flotation machine is commonly installed in roughing, scavenging and concentration stages of flotation plants, especially for processing copper ore, gold ore, lead-zinc ore, nickel ore, molybdenum ore, fluorite and other mineral resources.

Compared with conventional flotation equipment, the SF series flotation cell provides excellent adaptability for different ore characteristics, including coarse particle flotation, high-density slurry flotation and continuous industrial production.

Working Principle of SF Flotation Cell

The SF flotation cell adopts a vertical impeller structure driven by a motor. During operation, the impeller rotates rapidly and generates negative pressure in the lower part of the stator, allowing the flotation cell to automatically inhale air through the hollow shaft.

At the same time, the rotating impeller fully mixes the absorbed air with mineral slurry, creating numerous fine bubbles. Valuable mineral particles selectively attach to these bubbles under the action of flotation reagents and rise to the surface to form mineralized froth.

The froth layer is continuously removed by the scraper mechanism, while unwanted gangue minerals remain in the slurry and discharge through the tailing outlet.

The self-aspiration design enables:

• Automatic air suction without external blower
• Efficient slurry circulation and mixing
• Stable froth formation
• Improved mineral recovery performance

The SF flotation machine is suitable for both independent flotation cells and complete flotation circuits with multiple units connected in series.

Main Applications of SF Flotation Machine

Copper Ore Flotation

SF flotation cells are widely used in copper beneficiation plants for recovering copper sulfide minerals such as chalcopyrite. The equipment provides strong agitation capability and effective bubble generation, improving copper recovery rates in roughing and cleaning processes.

Typical applications:

• Copper sulfide flotation
• Copper concentrate upgrading
• Copper tailings recovery

Gold Recovery Flotation

For gold processing plants, the SF flotation machine is commonly used for recovering fine-grained gold associated with sulfide minerals.

Applications include:

• Gold ore flotation
• Sulfide gold recovery
• Gold concentrate production

Its strong mixing performance improves contact between mineral particles, reagents and air bubbles, enhancing flotation efficiency.

Lead-Zinc Ore Beneficiation

The SF series flotation cell is suitable for selective separation of lead and zinc minerals.

Typical applications:

• Galena flotation
• Sphalerite flotation
• Polymetallic ore separation

The flexible operation parameters allow operators to adjust flotation conditions according to different mineral compositions.

Non-Metallic Mineral Processing

Besides metal ores, SF flotation equipment is also applied in:

• Fluorite flotation
• Graphite flotation
• Phosphate flotation
• Silica sand purification
• Industrial mineral upgrading
