Magnetic Separation Beneficiation Plant
Magnetic separation beneficiation plants are high-efficiency process facilities that enable the separation of valuable magnetic minerals within the ore from gangue minerals by means of differences in magnetic properties.
They are effectively used in the beneficiation of iron ore primarily, as well as chromium, magnetite, hematite, and various industrial minerals.
Our plants, designed with a modern engineering approach, are engineered with the objective of maximum recovery and low operating cost.
Process Flow Sheet
Magnetic beneficiation plants have an integrated and optimized process flow:
1. Ore Feeding and Crushing
Run-of-mine ore is fed to the crushing unit in order to be reduced to the appropriate particle size.
2. Grinding
The ore is ground to the target particle size in order to ensure mineral liberation.
3. Classification
The ground material is separated according to particle size, and the appropriate fraction for magnetic separation is prepared.
4. Magnetic Separation
This is the main process step of the plant.
Under the effect of a magnetic field:
Magnetic minerals (for example, magnetite) adhere to the surface of the magnetic drum.
Non-magnetic gangue minerals are removed from the system.
Depending on the technology used, systems can be designed as:
Low Intensity Magnetic Separation (LIMS)
High Intensity Magnetic Separation (HIMS)
Wet or Dry Magnetic Separation
5. Concentrate Thickening and Filtration
The concentrate obtained is generally in slurry form.
The solids ratio is increased with a thickener.
The moisture content is reduced with a filter press or vacuum filter.
The final product is made ready for shipment.
6. Tailings Management
The non-magnetic residual material is directed to:
A tailings storage facility
A backfilling system
All processes are designed in compliance with environmental regulations.
