An electromagnetic wheel is used in the magnetic separation process of ore from gangue as it seperates the magnetic particles from the non-magnetic particles.The magnetic particles get attracted to the magnetic wheel and thus get seperated from the gangue.Iii in the froth floatation process, the ore floats on the top the gangue settles.
In magnetic separations, particularly those involving capture and elution of target, the exact size of the magnetic particle may be unimportant provided that the particles are in some general size range and offer desired separation characteristics.Diameter also determines surface area.
