A Wet Magnetic Separator is a device used to separate and recover magnetic minerals from non-magnetic materials in a wet processing environment. It is widely used in mineral processing, recyclage, and other industries where magnetic separation is required.

Principales fonctionnalités:
1. Wet Processing – Operates with water or slurry, making it suitable for fine particles.
2. Magnetic Field – Uses permanent magnets or electromagnets to attract magnetic materials.
3. High Efficiency – Effective for separating weakly magnetic minerals like hematite, limonite, and ilmenite.
4. Adjustable Intensity – Some models allow control over magnetic field strength.

Types of Wet Magnetic Separators:
1. Drum-Type Magnetic Separator
- A rotating drum with an internal magnet attracts magnetic particles while non-magnetics flow away.
- Used in iron ore beneficiation and heavy media recovery.

2. High-Gradient Magnetic Separator (HGMS)
- Uses a matrix (steel wool or grooved plates) to capture fine weakly magnetic particles.
- Common in kaolin clay purification and rare earth mineral processing.

3. Vertical Ring & Pulsating High-Gradient Magnetic Separator (VPHGMS)
- Combines pulsating fluid flow with high-gradient fields for better separation efficiency.

4. Wet Belt Magnetic Separator
- Uses a conveyor belt system to continuously remove ferrous materials from slurries.

Applications:
- Iron ore beneficiation (magnétite, hématite).
- Heavy media recovery in coal washing.
- Purification of non-metallic minerals (quartz, feldspath).
- Recycling of metals from industrial waste streams.

Avantages:
- High recovery rate for fine particles.
- Low operational cost compared to dry separators.
- Can handle large volumes of slurry efficiently.

Limites:
- Requires water, which may need treatment before disposal.
- Not suitable for extremely coarse materials.
