Product Description

High Pressure Feed Jet Flotation Column

The ZFJS flotation column uses a high-pressure slurry feeding system combined with jet-induced air aspiration. A jet device installed on the top feed pipeline creates negative pressure as the slurry passes through at high velocity, drawing air into the slurry stream.
Intensive gas-liquid interaction disperses the aspirated air into fine bubbles and promotes flotation mineralization. The configuration also allows a relatively compact column structure with an approximate height of 3–4 m.

Key Features

High-Pressure Slurry Feeding

The ZFJS uses a high-pressure slurry feed arrangement as an important part of its jet aeration process.

Feed-Pipeline Jet Aeration

The jet aspiration device is arranged on the slurry feed pipeline at the top of the flotation column, creating a direct feed-and-aeration configuration.

Negative-Pressure Air Aspiration

High-velocity slurry passing through the jet device generates negative pressure, drawing air into the slurry stream.

Fine Bubble Generation

Intensive gas-liquid interaction disperses the aspirated air into fine bubbles, supporting flotation mineralization.

Compact Column Arrangement

The ZFJS can use a column height of approximately 3–4 m, reducing the vertical space required for equipment installation.

Fewer Jet Devices

The configuration requires fewer jet devices, simplifying the jet aeration arrangement.

Technical Characteristics

Working Principle

High-pressure slurry enters through the top feed pipeline and passes through the jet aspiration device.

The high-velocity slurry creates negative pressure, drawing air into the slurry stream. Intensive gas-liquid interaction then disperses the aspirated air into fine bubbles.

The interaction between mineral particles and fine bubbles promotes flotation mineralization, after which separation takes place inside the flotation column.

Application

The ZFJS flotation column is particularly suitable for mineral flotation projects where:

• Vertical installation height is limited

• A compact flotation column arrangement is required

• Jet-induced air aspiration is preferred

• High-pressure slurry feeding is available

• A simplified jet arrangement is required

Final equipment selection should be determined according to mineral characteristics and actual flotation process conditions.

Equipment Selection

For ZFJS equipment selection and quotation, please provide:

• Mineral or material type

• Required processing capacity

• Feed particle size

• Slurry concentration

• Feed grade

• Target concentrate grade

• Recovery requirements

• Existing flotation process

• Available installation height

For new materials or uncertain flotation conditions, laboratory or pilot-scale flotation testing can be carried out before industrial equipment selection.

FAQ

1. How does the flotation column introduce air?

The ZFJS uses a jet aspiration device installed on the top slurry feed pipeline. High-velocity slurry generates negative pressure through the jet device and draws air into the slurry stream.

2. How are fine bubbles generated?

Aspirated air interacts intensively with the high-velocity slurry. The gas-liquid interaction disperses the air into fine bubbles for flotation mineralization.

3. What is special about the ZFJS feed arrangement?

The ZFJS combines high-pressure slurry feeding with a jet aspiration device located on the top feed pipeline, integrating slurry feeding and jet-induced aeration.

4. What information is required for ZFJS equipment selection?

Mineral type, processing capacity, particle size, slurry concentration, feed grade, concentrate requirements, flotation conditions and available installation height should be provided.
