Abstract
A ferrofluid sink/float separator for separating nonmagnetic materials of different densities comprises a horizontal separating tank and a magnetic field generating mechanism. The separating tank is filled with a ferrofluid capable of being induced by the magnetic field generating mechanism to have a magnetic field gradient and various apparent densities in the direction of earth gravity. The magnetic field generating mechanism comprises two magnetic poles spaced at an interval and a gap which is defined by the two magnetic poles and is located under the horizontal separating tank.
