High Intensity Magnetic Separator

Product Introduction

Wet Drum High Intensity Magnetic Separator (WHIMS) is an advanced mineral processing equipment designed for efficient separation and recovery of magnetic minerals from non-magnetic materials. It is widely used in mining, beneficiation plants, and industrial mineral purification applications where high recovery rate, separation accuracy, and stable operation are required.

As one of the most important types of Mining Magnetic Separation Equipment, the wet drum magnetic separator is commonly applied in iron ore beneficiation, hematite upgrading, ilmenite recovery, manganese ore processing, silica sand purification, feldspar purification, kaolin upgrading, and other mineral processing industries.

Compared with traditional gravity separation or flotation processes, magnetic separation provides a chemical-free and environmentally friendly beneficiation solution. By using a specially designed magnetic system, the equipment generates strong magnetic force and high magnetic field gradient to effectively capture magnetic and weakly magnetic particles while allowing non-magnetic materials to flow through the separation zone.

The machine adopts a rotating magnetic drum structure with optimized magnetic field distribution. During operation, mineral slurry enters the separation tank, and magnetic particles are attracted onto the drum surface under magnetic force. The rotating drum transports the recovered magnetic concentrate away from the slurry area and discharges it continuously, while non-magnetic tailings are discharged separately.

Depending on mineral characteristics and processing requirements, different magnetic separation technologies can be selected, including:

• LIMS (Low Intensity Magnetic Separator) for strongly magnetic minerals such as magnetite and ferrosilicon recovery.
• MIMS (Medium Intensity Magnetic Separator) for medium magnetic susceptibility minerals.
• HIMS (High Intensity Magnetic Separator) for weakly magnetic minerals including hematite, ilmenite and manganese ore.
• HGMS (High Gradient Magnetic Separator) for fine particle and weak magnetic mineral recovery.
• VPHGMS (Vertically Pulsating High Gradient Magnetic Separator) for ultra-fine weak magnetic minerals and non-metallic mineral purification.

International mining companies commonly use high gradient magnetic separation technology for recovering fine weakly magnetic minerals and improving concentrate grade.

Application Areas

1. Iron Ore Beneficiation

Iron ore processing is the most important application of magnetic separators. The equipment is widely used for upgrading:

• Magnetite (Fe3O4)
• Hematite (Fe2O3)
• Limonite
• Titanomagnetite

The magnetic separator improves iron recovery by removing gangue minerals and producing higher-grade iron concentrate for steel production.

For magnetite concentration, LIMS wet drum magnetic separators are commonly applied because of their high capacity and excellent recovery performance.

2. Silica Sand and Quartz Purification

In glass-grade silica sand production, even a small amount of iron contamination can reduce product quality.

The magnetic separator removes:

• Iron oxide impurities
• Ferrous mineral particles
• Weak magnetic contaminants

Applications include:

• Quartz sand purification
• Glass sand processing
• High-purity silica production

3. Non-metallic Mineral Processing

High intensity and high gradient magnetic separators are widely used for purification of:

• Feldspar
• Kaolin clay
• Wollastonite
• Fluorite
• Ceramic minerals

The equipment improves whiteness and product quality by removing iron-bearing impurities.

4. Battery Mineral and Strategic Mineral Processing

With the rapid development of renewable energy industries, magnetic separation technology is increasingly used in:

• Lithium ore beneficiation
• Spodumene processing
• Rare earth mineral upgrading
• Tantalite and coltan separation

High gradient magnetic separation is especially suitable for fine particles and weak magnetic minerals that cannot be efficiently recovered by conventional magnetic separators.

Working Principle

The wet drum magnetic separator works based on the difference in magnetic susceptibility between minerals.

During operation:

1. Mineral slurry enters the separation tank.
2. Magnetic particles are attracted by the magnetic field.
3. Magnetic minerals attach to the rotating drum surface.
4. The drum carries magnetic concentrate away from the slurry.
5. Non-magnetic minerals flow out as tailings.
6. Concentrate is discharged automatically after leaving the magnetic field.

The magnetic field intensity and drum configuration can be customized according to:

• Mineral type
• Feed particle size
• Required concentrate grade
• Recovery target
