Importance of Particle Size in Mineral Magnetic Separation

Particle size is one of the most important parameters in magnetic separation.
Different particle sizes can have different:
Magnetic responses
Flow characteristics
Trajectories
Residence times
Surface interactions
A mineral containing both coarse and fine particles may therefore require careful feed preparation or classification before magnetic separation.
For some applications, screening or classification before magnetic separation can improve the consistency of the material presented to the separator.
