Mineral processing operations handle a wide range of materials, from coarse minerals and aggregates to fine powders and processed concentrates. During extraction, transportation, grinding, screening, and processing, ferrous metal can enter the material stream from equipment wear, tools, conveyor components, and other sources.

Magnocan provides magnetic traps and magnetic separation solutions for mineral processing applications, helping remove unwanted ferrous contamination while supporting product quality and protecting downstream processing equipment.

Improve Mineral Purity with Magnetic Separation

Magnetic separation is an important step in many mineral processing applications where ferrous contamination needs to be controlled.

By placing magnetic equipment at strategic points in the process, operators can capture ferrous particles before they move further through the production line.

Magnetic separation can help:

  • Remove unwanted ferrous particles
  • Improve the cleanliness of processed minerals
  • Protect downstream equipment
  • Reduce the risk of metal-related equipment damage
  • Support consistent material quality
  • Provide continuous separation during material handling

The appropriate magnetic system depends on the mineral characteristics, particle size, moisture content, flow rate, and processing conditions.

Removing Ferrous Contamination from Mineral Streams

Ferrous contamination can enter mineral streams from many sources throughout a processing operation.

Common sources include:

  • Conveyor components
  • Crusher and mill wear
  • Steel tools and maintenance equipment
  • Processing machinery
  • Structural components
  • Broken or worn equipment parts

Even relatively small pieces of ferrous metal can create problems when they reach sensitive processing equipment.

Magnetic traps and separators can be installed at suitable points to capture this material before it reaches downstream stages.

Common Applications

Mineral processing covers a wide range of materials and production conditions. Magnetic separation equipment can be configured for different material types and processing environments.

Mineral Powders

Fine mineral powders can contain ferrous particles introduced during grinding, milling, conveying, or handling.

Magnetic separation equipment can be incorporated into powder-processing systems to help capture unwanted ferrous contamination.

Fine Materials

Fine and granular mineral materials can be processed through suitable magnetic separation equipment depending on their flow characteristics and throughput.

The separator configuration should account for material depth, particle size, flow rate, and the required level of separation.

Dry Processing

Dry mineral processing systems can use magnetic grates, drawer-style separators, suspended magnets, magnetic drums, and other configurations depending on the application.

These systems can be installed at hoppers, chutes, conveyors, transfer points, and other material-flow locations.

Wet Processing

Wet mineral-processing applications require different equipment configurations because water, slurry density, viscosity, and flow conditions can affect magnetic separation.

Magnocan can evaluate the process conditions to help determine an appropriate magnetic separation solution.

Magnetic Separation Equipment for Mineral Processing

Magnocan offers magnetic separation solutions that can be configured for different mineral-processing applications.

Depending on the material and process, equipment may include:

  • Magnetic traps
  • Magnetic grates
  • Drawer magnets
  • Pipeline magnets
  • Suspended magnetic separators
  • Overband magnetic separators
  • Magnetic drums
  • Magnetic pulleys
  • Custom magnetic separation systems

The correct equipment depends on the application rather than simply the material being processed.

Factors such as particle size, material depth, throughput, moisture, belt speed, contamination size, and installation location should be considered during equipment selection.

Protecting Downstream Processing Equipment

Ferrous metal entering a processing system can potentially damage equipment or cause unplanned interruptions.

Magnetic separation can provide an additional protection stage before sensitive equipment such as:

  • Crushers
  • Mills
  • Screens
  • Pumps
  • Conveyors
  • Classifiers
  • Processing machinery

Installing magnetic separation upstream of critical equipment can help intercept ferrous contaminants before they reach these components.

For high-value processing equipment, the location of the magnetic separator is particularly important. A system may be more effective when positioned close to the potential contamination source or before vulnerable equipment.
