Flotation Test Machine

The versatile Laboratory Flotation Bench has been designed to provide an accurate and reliable means of reproducing test results. It is ideally suited for duplicating plant processes and operations. Several configurations are available for impeller style and diffuser arrangement.

The flotation machine is used in mineral processing to separate valuable minerals from gangue (unwanted material) based on differences in hydrophobicity (ability to repel water) and buoyancy. Flotation machines are widely used in the mining industry for ore beneficiation and concentration processes.

Importance :

• Flotation machines play a crucial role in recovering valuable minerals from ores by exploiting differences in surface properties. This enables separation and concentration of desired minerals and production of valuable concentrates.

Control System :

• Digital control by touch screen

Capacity :

• Flotation cell capacities from 0.2 to 7 litres

Applications :

• Flotation
• Attritioning
• Blending
• Agitating

Construction :

• Standard acrylic cells and stainless steel impellers (other materials on request)
• Cells and impellers for high-temperature flotation made from stainless steel
• All wetted metal parts made of high-quality 316 stainless steel

Working Principle :

Impeller System :

• Each cell contains an impeller that stirs the slurry and creates a turbulent environment for thorough mixing of reagents and ore particles.

Air Supply :

• Air is introduced into the flotation cell via blowers or spargers. Generated air bubbles carry hydrophobic mineral particles to the surface.

Reagent Addition :

• Specific reagents are added to modify hydrophobicity and promote selective attachment to air bubbles. These include collectors, frothers, and modifiers depending on the mineral type.

Froth Laundering :

• Hydrophobic particles form a froth layer at the surface, which is continuously removed using paddles or overflow launders.

Adjustable Parameters :

• Impeller rotation speed and direction
• Airflow rate
• Froth depth
• Pulp density
• These parameters allow optimization of flotation performance based on mineral characteristics and required outcomes.
