Magnetic separation solutions depend on your material, contamination type, processing conditions and separation requirements. Explore Corvelan applications to find suitable magnetic separator options for different industries and materials.
Quick Answer
Where Is Magnetic Separation Used?
Industrial magnetic separation is used to recover magnetic minerals, remove ferrous contamination, purify materials, recover iron and steel from recycling streams, and protect crushers, mills, shredders and other downstream equipment. The right separator depends on your material type, contamination challenge, installation conditions and separation requirements.
Selection principle: the strongest magnet is not automatically the best separator. Real separation performance depends on the actual working distance, material condition and how effectively the separator can capture and discharge the target material.

Application Guide
Magnetic Separation by Industry and Material
This guide helps you understand suitable magnetic separator solutions for different materials and applications. The right equipment depends on your material type, separation requirements and installation conditions.
| Application | Main Objective | Typical Target | Starting Magnetic Separator Types |
|---|---|---|---|
| Iron Ore | Mineral recovery or rejection | Magnetite and other responsive iron minerals | Magnetic drum or other ore-specific magnetic separation route |
| Silica Sand | Purification | Free ferrous, magnetite and selected weak magnetic impurities | Pre-cleaning drum, dry high-intensity or wet high-gradient route |
| Kaolin | Purification | Iron-bearing and discoloring magnetic mineral impurities | High-intensity or high-gradient route after material review |
| Titanium Ore | Beneficiation | Magnetite, titanomagnetite and selected ilmenite-related fractions | Test-based staged magnetic separation route |
| Coal | Equipment protection / ferrous removal | Bolts, wire, rods and steel fragments | Suspended magnet, overband, head pulley or drum by installation location |
| Conveyor | Tramp iron removal | Ferromagnetic metal in moving bulk material | Manual suspended or self-cleaning overband magnetic separator |
| Scrap Metal | Ferrous recovery | Liberated iron and steel | Magnetic drum, overband or magnetic head pulley |
| Tire Recycling | Steel wire recovery | Liberated tire bead and steel wire | Magnetic drum, overband or head pulley by line position |
Do not compare separators by surface Gauss alone. Ask what field reaches the target at the real working distance, whether the target is liberated, how it moves through the separation zone and how the captured fraction will be discharged.
Information Needed for Equipment Selection
How to Choose the Right Magnetic Separator
A reliable recommendation starts with understanding your material, application requirements and operating conditions. These six inputs normally determine whether a proposed magnetic separator option is technically sensible enough to move into detailed configuration.
01 · Material
Material Type
Ore, sand, powder, coal, shredded scrap, rubber or another bulk material. Bulk density and flow behavior may affect presentation.
02 · Target
Separation Target
Tramp iron, magnetic mineral, ferrous recovery fraction or magnetic impurity. The target defines what must move in the field.
03 · Liberation
Particle Size & Liberation
A stronger magnetic field cannot separate material that is still locked inside another particle or composite piece.
04 · Feed
Feed Condition
Dry, wet, slurry, sticky, free-flowing, stable or highly variable. The separator must match how the real feed reaches the magnetic zone.
05 · Capacity
Throughput & Layer Depth
Capacity, material depth and feed consistency affect separation performance and equipment selection.
06 · Position
Installation Location
Common installation locations include conveyors, head pulleys, chutes and processing lines. The installation location affects both equipment design and separation performance.

Magnetic Separator Types
Magnetic Separator Types Used Across These Applications
The equipment family should follow the separation duty and installation location. One separator type should not be forced into every material just because it appears in a catalog.
Magnetic Drum
Useful for continuous magnetic/non-magnetic discharge with controlled bulk feed, mineral duties and ferrous recovery.
Suspended Magnet
A common solution for occasional tramp iron removal above conveyor-fed bulk material.
Self-Cleaning Overband
Better suited where captured ferrous loading is frequent and automatic reject discharge is required.
Magnetic Head Pulley
Integrates the separation point with the conveyor discharge trajectory for continuous ferrous separation.
High-Intensity Route
Reviewed for selected weakly magnetic mineral impurities where conventional strongly magnetic separation is insufficient.
Typical Scenarios
Common Magnetic Separation Applications
These examples show common magnetic separation challenges across different industries. Final equipment recommendations depend on the actual material and application conditions.
Mineral Purification
For silica sand and kaolin, identify whether the unwanted iron is free, strongly magnetic, weakly magnetic or locked before choosing the magnetic stage.
Conveyor Equipment Protection
For coal and bulk handling, define burden depth, working distance, belt speed, target tramp iron and reject path before selecting suspended equipment.
Ferrous Recovery
For scrap and tire recycling, recovery begins with liberation. Shredding and feed control often determine whether the magnetic stage can separate the ferrous fraction cleanly.

FAQ
Magnetic Separation Application Questions
What industries use magnetic separation?
Magnetic separation is widely used in mining, mineral processing, silica and industrial mineral purification, coal handling, aggregate and bulk material handling, metal recycling, tire recycling and other processes where responsive magnetic material must be recovered or removed.
How do I choose a magnetic separator for my application?
Start with the separation target, material condition, particle size, liberation, throughput, feed depth, magnetic response and installation location. Then select the separator family that can present the target effectively to the working field and discharge the captured fraction safely.
What is the difference between tramp iron removal and mineral magnetic separation?
Tramp iron removal normally targets unwanted ferromagnetic steel or iron pieces that can damage equipment or contaminate product. Mineral magnetic separation uses differences in mineral magnetic response to recover, reject or stage mineral fractions within a beneficiation or purification flowsheet.
Does higher Gauss always mean better magnetic separation?
No. A Gauss value is meaningful only when the measurement position and method are defined. Separation also depends on field gradient, real working distance, target size and shape, magnetic susceptibility, feed depth, material motion, liberation and discharge geometry.
What magnetic separator is used for mineral beneficiation?
The route depends on mineralogy and magnetic response. Strongly magnetic minerals may fit conventional drum separation, while weaker magnetic mineral targets may require higher-intensity or high-gradient equipment. Representative testing is important when mineral response or liberation is uncertain.
Can magnetic separation recover non-ferrous metals?
Conventional magnetic separators primarily recover or remove responsive ferrous and magnetic material. Free aluminum, copper and brass normally require another downstream separation technology after ferrous removal.
Should I use dry or wet magnetic separation?
Choose from the real feed condition and mineral response. Dry separation can fit free-flowing bulk material, while fine slurry applications may require wet high-gradient routes. Wet is not automatically better, and dry is not automatically simpler if the material does not present consistently.
What information does Corvelan need before recommending a separator?
Send the material, particle size, throughput, feed condition, target magnetic fraction or contaminant, required result, installation location and any available drawings or photos. For weakly magnetic mineral work, representative material and mineralogical information are especially useful.
