Recent developments in magnetic methods of material

2003-9-1  In dry magnetic separation where F d is usually negligible, the particle size, as a rule, does not affect the efficiency of separation significantly because of the same particle size dependence of the magnetic force and of the force of gravity. On the other hand, in wet separation where the hydrodynamic drag can be important, selectivity of the ...
