Recovery enhancement of magnetite fines in magnetic separation

2004-1-23  In the magnetic separation of fine particles, magnetic forces must overcome the hydrodynamic drag forces but magnetic forces must be greater than the gravity forces for the coarse mineral particles. It has been shown that conditions conducive to wet magnetic separation prevail in the particle range of around 5–10 to 2000–3000 μm.
