Wet High Intensity Magnetic Separator

High-intensity wet magnetic separator designed for separating weakly magnetic (paramagnetic) minerals such as wolframite from non-magnetic materials.
Used for concentration, cleaning, and upgrading of fine mineral particles.

Working Principle

• Paramagnetic particles are attracted under a high-intensity magnetic field with strong flux gradients.
• Magnetic flux is concentrated using specially designed pole structures and media (such as expanded metal sheets).
• Non-magnetic particles are carried away by the slurry, while magnetic particles are retained and collected.

Performance Data (Examples)

• Concentrate grade: up to ~63.98% WO₃
• Recovery: up to ~95.47%
• Effective fine particle recovery up to micron-level sizes

Additional Information

• High-gradient magnetic separators (HGMS) are also used for improved efficiency
• Magnetic separation efficiency depends on flux gradient, particle size, and magnetic susceptibility
• Sharp-edged magnetic poles improve separation performance
